120-120: Consider improving the Estonian translation.The current translation "Ootel {{source}}" is understandable but could be more natural. Consider using one of these alternatives:
- "Ootab {{source}}" (actively waiting for)
- "Ootan {{source}}" (waiting for)
- 'waiting-for': 'Ootel {{source}}', + 'waiting-for': 'Ootab {{source}}',locales/file-uploader/fi.js (1)

2-2: Consider updating social-source-lang to match locale-id.The
social-source-langis set to 'en' whilelocale-idis 'fi'. This seems inconsistent with other locale files where both values match.- 'social-source-lang': 'en', + 'social-source-lang': 'fi',locales/file-uploader/hy.js (1)
120-120: Consider revising the translation to use a neutral form.The current Armenian translation uses first person ("I am waiting") while other languages use a neutral form. Consider changing "Սպասում եմ" to a more neutral form to maintain consistency across translations.

120-120: Consider adjusting the translation perspective.The Georgian translation uses first person ("I am waiting") while other languages use a more neutral form. Consider changing to a neutral form for consistency across languages:
- 'waiting-for': 'ველოდები {{source}}', + 'waiting-for': 'ველოდება {{source}}',locales/file-uploader/cs.js (1)
125-125: Consider using a verb form for consistency.The Czech translation uses a noun form ("Čekání") while most other languages use a verb form. Consider changing to a verb form for consistency:
- 'waiting-for': 'Čekání na {{source}}', + 'waiting-for': 'Čeká se na {{source}}',blocks/ProgressBar/progress-bar.css (2)
Line range hint
15-20: Consider adding transform optimization for better performance.While the current implementation works, using
transform: scaleX()instead of width can provide better performance as it triggers compositing instead of layout recalculation.Consider this optimization:
position: absolute; - width: calc(var(--l-progress-value) * 1%); + width: 100%; height: 100%; background-color: var(--uc-primary); - transform: translateX(0); + transform-origin: left; + transform: scaleX(calc(var(--l-progress-value) / 100)); opacity: 1; transition: - width 0.6s, + transform 0.6s, opacity 0.3s;
51-59: Simplify transform calculation in keyframes.The current calculation
calc(100 / var(--l-fake-progress-width) * 100 * 1%)can be simplified.Consider this simplification:
@keyframes fake-progress-animation { from { transform: translateX(-100%); } to { - transform: translateX(calc(100 / var(--l-fake-progress-width) * 100 * 1%)); + transform: translateX(calc((100 - var(--l-fake-progress-width)) * 1%)); } }

31-37: 🛠️ Refactor suggestion
Simplify progress reset logic and fix event listener issues.
The current implementation adds unnecessary complexity and has potential memory leaks.
Consider this simplified implementation:
if (value === 0 && prevValue > 0) { - this.ref.realProgressLine.addEventListener('transitionend', () => { - this.style.setProperty('--l-progress-value', this._value.toString()); - }); - return; } this.style.setProperty('--l-progress-value', this._value.toString());The CSS property can be updated immediately as the transition will handle the animation smoothly.

Thoroughly test & benchmark the code to ensure it meets the requirements.if (value === 0 && prevValue > 0) { } this.style.setProperty('--l-progress-value', this._value.toString());
22-29:
⚠️ Potential issueFix potential memory leaks and race conditions in event handling.
The current implementation has several issues:
- Event listeners are added without cleanup, potentially causing memory leaks
- Multiple listeners could be added if value changes rapidly
- One-time event listeners are not properly cleaned up
Consider this implementation:
if (value === 100) { - this.ref.realProgressLine.addEventListener('transitionend', () => { - this.ref.realProgressLine.classList.toggle('uc-progress--hidden', true); - }); + const hideProgress = () => { + this.ref.realProgressLine.classList.toggle('uc-progress--hidden', true); + this.ref.realProgressLine.removeEventListener('transitionend', hideProgress); + }; + this.ref.realProgressLine.addEventListener('transitionend', hideProgress, { once: true }); } this.ref.fakeProgressLine.classList.toggle('uc-fake-progress--hidden', value !== 0);📝 Committable suggestion

30-44: 💡 Codebase verification
Browser compatibility and accessibility improvements needed
- Remove or provide fallback for non-standard
transition-behaviorproperty- Add reduced motion support:
@media (prefers-reduced-motion: reduce) { uc-progress-bar .uc-fake-progress { animation-duration: 3s; /* Slower animation */ /* Or completely disable: animation: none; */ } }
- Consider using CSS
@supportsrule for transition-behavior when browser support improves🔗 Analysis chain
Address browser compatibility and performance concerns.
- The
transition-behaviorproperty has limited browser support- Continuous animation might impact performance on low-end devices
Run this script to check browser compatibility:
Consider adding:
- A fallback for browsers that don't support
transition-behaviorwill-change: transformfor better performance- Reduced animation on reduced-motion preference

47-50: Enhance accessibility with ARIA attributes.The progress bar template should include ARIA attributes to improve accessibility.
Consider this enhancement:
ProgressBar.template = /* HTML */ ` - <div ref="fakeProgressLine" class="uc-fake-progress"></div> - <div ref="realProgressLine" class="uc-progress"></div> + <div ref="fakeProgressLine" class="uc-fake-progress" role="progressbar" aria-hidden="true"></div> + <div ref="realProgressLine" class="uc-progress" role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="0"></div> `;Don't forget to update the aria-valuenow attribute when the progress value changes:
this.style.setProperty('--l-progress-value', this._value.toString()); + this.ref.realProgressLine.setAttribute('aria-valuenow', this._value.toString());

28-28: LGTM! Clear and correct visibility toggle logic.The fake progress line visibility is properly toggled based on the progress value.
37-37: LGTM! Efficient progress value update.Good use of CSS custom property for progress value updates, which is performant and maintainable.
41-42: Consider potential race condition with completion handler.While the visibility toggle logic is correct, there could be a race condition if visibility changes while a completion transition is in progress.
Consider adding a check in the completion handler:
defineAccessor('visible', (visible) => { this.ref.realProgressLine.classList.toggle('uc-progress--hidden', !visible); this.ref.fakeProgressLine.classList.toggle('uc-fake-progress--hidden', !visible); + // Reset completion state when showing + if (visible && this._value === 100) { + this._value = 0; + } });

22-32: LGTM! Memory leak fixed, but consider debouncing.The event listener cleanup is now properly handled with
once: true. However, rapid value changes near 100% could still cause visual glitches.Consider debouncing the transition:
if (value === 100) { + clearTimeout(this._hideTimeout); + this._hideTimeout = setTimeout(() => { this.ref.realProgressLine.addEventListener( 'transitionend', () => { this.ref.realProgressLine.classList.toggle('uc-progress--hidden', true); }, { once: true, }, ); + }, 100); }

34-34: LGTM! Clear and correct visibility toggle.The fake progress line visibility logic is appropriate, showing it only during initial loading state.
49-49: LGTM! Clean progress value update.Using CSS custom properties for progress value is a good practice for performance.
53-54: LGTM! Consistent visibility handling.Both progress lines are toggled consistently, maintaining visual coherence.
59-62: LGTM! Clean template structure.The template is minimal and properly structured with appropriate ref attributes.

7-9: LGTM!The
_visibleproperty is well-documented and has a sensible default value.
24-34: LGTM!The event listener is properly cleaned up using the
onceoption, which addresses the memory leak concerns from previous reviews.
36-36: LGTM!The fake progress line visibility toggle is correctly implemented.
39-51: LGTM!The reset handling is properly implemented with cleanup of the event listener using the
onceoption.
63-66: LGTM!The template structure is clean with properly defined references for both progress lines.

37-48: Improve reset transition handling.The reset transition event listener could be enhanced with error handling and cleanup on component destruction.
Consider this implementation:
if (value === 0 && prevValue > 0) { + const handleResetTransition = () => { + try { + this.style.setProperty('--l-progress-value', this._value.toString()); + } catch (error) { + console.error('Failed to update progress value:', error); + } + }; + this.ref.realProgressLine.addEventListener( 'transitionend', - () => { - this.style.setProperty('--l-progress-value', this._value.toString()); - }, + handleResetTransition, { once: true, }, ); + + // Cleanup on component destruction + this.destructors.push(() => { + this.ref.realProgressLine.removeEventListener('transitionend', handleResetTransition); + }); return; }
