Desktop app shows Invalid 1 panel layout error when resizing down

[NevilleQingNY]

Summary

A user reported an Unexpected Application Error in the Multica desktop app while resizing the app window down.

The visible error message is:

Invalid 1 panel layout: 69.662%, 30.338%

The screenshot appears to show the default React Router error page, suggesting this is a frontend renderer/runtime error rather than a native Electron crash.

Context

The report came from the desktop app while the user was sizing the window down. We have not fully confirmed the exact route or reproduction path yet.

Current suspicion: a responsive layout path involving react-resizable-panels, where a panel group may restore a saved two-panel layout while only one panel is currently registered/rendered.

Open questions

• Which page/tab was active when the error appeared?
• Was the app zoomed in, or at default zoom?
• Does the issue reproduce consistently when resizing the desktop window down?
• Is this specific to Project Detail, Issue Detail, Inbox, or another route?

Thanks for the report. I opened PR #5626 with a fix: #5626

Root cause: ProjectDetail kept ResizablePanelGroup mounted on mobile while rendering only the content panel, so a restored desktop two-panel layout could be validated against one mounted panel during resize.
Fix: Mobile project detail now renders the main content directly and uses the sidebar sheet outside the resizable group, while desktop keeps the persisted two-panel split.
Validation: pnpm --filter @multica/views exec vitest run projects/components/project-detail.test.tsx, pnpm --filter @multica/views typecheck, and pnpm --filter @multica/views lint pass. make check-worktree was attempted but local Docker is not running, so the PostgreSQL preflight could not start.

I will keep an eye on CI and review feedback.
