[Bug]: Citation preview stays above the command palette when pressing Cmd+K #36847
Description
Before submitting
- I searched existing issues and did not find a duplicate.
- I included enough detail to reproduce or investigate the problem.
Area
apps/web
Steps to reproduce
- Open a thread containing a message with a citation.
- Open the citation preview, so its quoted text, comment and Go to source button are visible.
- With that preview still open, press Cmd+K to open the command palette.
Expected behavior
The citation preview closes when the command palette opens, leaving the palette unobstructed.
Actual behavior
Both overlays remain visible. The citation preview is drawn above the command palette and covers its search field and command results.
Impact
Minor bug or occasional failure: the preview obscures commands when switching to the palette.
Version or commit
Installed desktop app: 0.1.9-nightly.20261111.4515, read from its application metadata. The exact build at screenshot capture was not separately recorded.
Environment
macOS, T3 Code Nightly desktop. This is a UI overlay issue; provider/model is not relevant to the reported interaction.
Evidence and investigation
The reporter supplied a screenshot showing the command palette behind an open citation preview, with the preview's Go to source button visible. The preview covers the palette's upper-right area and several command rows. Private project and conversation text is omitted from this report.
A possible contributing cause in the source inspected at main @ ed05c0e43b: the shared popover positioner uses z-[130] in apps/web/src/components/ui/popover.tsx, while the command-dialog viewport uses z-50 in apps/web/src/components/ui/command.tsx. An existing popover can therefore appear above the palette if it is not dismissed. This is source inspection, not an independent browser reproduction, and the screenshot's build may differ from that source snapshot.
Workaround
Close the citation preview before opening the command palette.

While preparing a fix PR, I found that the exact citation-preview UI in this report was already removed by merged PR #34181 (commit
1a8ecc64b7126d312bb0873f1500e525be12fa2f, merged November 11).That change replaces the sent-message citation chip and its preview containing Go to source with an inline quote card. Clicking the card navigates directly to the source. Current main renders
AssistantCitationEmbedfromChatMarkdown.tsx; the old citation preview branch is gone.I missed this in the initial source inspection. The shared popover/palette stacking values noted in the report are real, but they do not establish that this removed citation-preview flow still exists on main.
Release ancestry checked through GitHub's compare API:
v0.1.9-nightly.20261111.4515predates the change (139 commits behind the merge).v0.1.10-nightly.20261114.4695contains the change (0 commits behind the merge).Closing this report as addressed by #34181. No new PR is needed for this exact screenshot. This conclusion comes from the removed rendering path and release ancestry, not a new browser reproduction; it does not claim that every other popover/command-palette interaction is fixed.

This is the same problem as #34181, so I'm closing it in favour of that one. If it is different, say how and it will be reopened.
