66-78:⚠️ Potential issue | 🟠 MajorGuard against duplicate retry timers in
handleError.
onErrorcan fire more than once beforeerrorCountupdates. This can queue multiple timers and moveerrorCountpastmaxRetrieswithout settinghasFailed, which can leave the component blank (no image, no placeholder, no failure UI).💡 Proposed fix

79-108: Consider debouncing ResizeObserver callbacks for performance.The
ResizeObservercallback fires on every resize event, which could trigger multiplemeasureOverflowcalls in rapid succession during continuous resizing (e.g., window resize, dynamic content changes). While React batches state updates, debouncing could reduce unnecessary layout measurements.♻️ Optional: Add debouncing to ResizeObserver
useEffect(() => { const frameId = globalThis.requestAnimationFrame(() => { measureOverflow(); }); if (typeof ResizeObserver === "undefined") { const handleResize = () => { measureOverflow(); }; globalThis.addEventListener("resize", handleResize); return () => { globalThis.removeEventListener("resize", handleResize); globalThis.cancelAnimationFrame(frameId); }; } + let resizeFrameId: number | null = null; const observer = new ResizeObserver(() => { - measureOverflow(); + if (resizeFrameId !== null) { + globalThis.cancelAnimationFrame(resizeFrameId); + } + resizeFrameId = globalThis.requestAnimationFrame(() => { + measureOverflow(); + resizeFrameId = null; + }); }); if (visibleDescriptionRef.current) { observer.observe(visibleDescriptionRef.current); } return () => { observer.disconnect(); globalThis.cancelAnimationFrame(frameId); + if (resizeFrameId !== null) { + globalThis.cancelAnimationFrame(resizeFrameId); + } }; }, [measureOverflow]);🤖 Prompt for AI Agents

- Around line 89-110: The MIME checks in DropListItemContentMedia (using
media_mime_type -> normalizedMimeType) don't strip MIME parameters, so values
like "text/html; charset=utf-8" fall through; update the logic in the function
that computes normalizedMimeType to first remove any parameters (e.g., split on
';' and take the first part, then trim().toLowerCase()) before performing the
includes/equals checks for MediaType. Ensure the same normalized,
parameter-stripped value is used for the image/video/audio/model/gltf and
text/html comparisons and only call resolveMediaTypeFromUrl(media_url) as the
final fallback.
