Layout pass: running list

Running list of defects from the layout pass, with where each one goes. ✅ = this PR, ✔ = merged.

• ✔ cmux-next settings: Undo bar clears the last row, titles and density names line up (layout pass 1) #22785 Settings: the Undo bar covered the last row; group titles and density names didn't line up
• ✅ Markdown: the toolbar shrank to its content (border stopped at ~286px, "README.mdSaved")
• Next (this lane): chief-inspector orange latency bars, quick-surface transcript with no inset, harnesses rows without an icon, combobox gallery stretch, agent-activity broken-image glyphs, diff page's black file bars
• Handed off: transcript-density, message-actions, prompt-queue-edit, composer-scroll, activity-indicators, context-menus, newtab lanes; Cloud (cmux NEXT Cloud: a storefront with your plan's sizes and one-click Get, featured in the App Store #22772) and Changelog (cmux NEXT updates: the Updated card sums up the whole update by area #22810) are being reworked in open PRs

Summary

.ui-toolbar (ui.css, display: inline-flex) and .md-toolbar (display: flex) had the same specificity, so the stylesheet that loaded last won. In the gallery bundle that was ui.css, so the toolbar shrank to fit its content: its bottom border stopped about 286px in, and the file name ran into "Saved" because .md-file's flex: 1 had no room to grow. The rule now sits under its host (.md-toolbar-host > .md-toolbar), so it wins whatever order the bundle loads the stylesheets in. [data-cmux-md-toolbar="false"] still hides the toolbar, since that rule is more specific.

Testing

• scripts/web-lint.sh passed.

Observed / Not run

• Observed: before/after captures from the Linux gallery (Chromium, dark), at 420 and 1200px.
• Not run: the Mac app. I didn't check whether the app's own bundle loads the stylesheets in the same order. The fix holds either way.

Changelog

• Fixed: the Markdown viewer's toolbar spans the whole page again, and the file name no longer runs into "Saved".

Written by scripts/ci/classify_failures.py (ci-failure-attribution.yml); signatures are its SIGNATURES table. A machine verdict is the runner's fault, not this PR's; yours means the failing file is one this PR changes, also red on main that main's latest full suite fails the same way, seen on other PRs that it failed on another pull request's run lately.

red: web / Web status; base red: the same failure on the base bb709e3; does not block
red: web / react-apps-check; base red: the same failure on the base bb709e3; does not block
red: web / react-apps-check (1); base red: the same failure on the base bb709e3; does not block

Tour of 5f9e5be85c (run): no media. The tour did not run: only webview code changed (1 path(s)), which the gallery advisory run checks in Linux Chromium on the pull request (its artifact holds any captures); add the media-tour-mac label to tour it on a Mac.
