🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winRestore focus when the inline panel closes.
When focus remains on a panel descendant and the
rightPanel.toggleshortcut closes the panel,PreviewPanelShellmakes that descendant inert. The close path does not move focus to the right-panel toggle or another reachable control. Focus can therefore be cleared tobody, leaving keyboard users without a useful destination.Restore focus to the existing right-panel toggle when

Main already closes the menu whenever the panel is closed (pingdotgg#15686), so this drops the PR's inline-only duplicate and its tests that expected the menu to stay open in sheet, sidebar and embedded modes. It also drops a PanelLayoutControls prop that main removed from the shell test. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…trol Main removes the add-surface trigger and menu as soon as the panel closes, and the right-panel toggle relocates when the shell unmounts. Both dropped focus to the page body. Closing now hands body focus to the toggle, and the unmount cleanup also follows a toggle that was focused when it moved. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
This reverts d386ef1. Treating body focus at close as panel-owned also moved focus to the toggle after a user had clicked the timeline, which breaks typing into the composer, and the toggle unmounts before the shell cleanup in ChatView's real order. Focus on the add-surface trigger or menu, or on a toggle that relocates, is left as it is on main. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Problem
Closing the inline right panel (Files, Diff, Terminal, Browser…) leaves keyboard interaction behind in it. If focus was inside the panel, it falls to the page body, so the next Tab starts from the top of the page. While the panel animates closed, its hidden controls also stay tabbable:
pointer-events-nonestops the mouse but not the keyboard.This is a small, obvious accessibility fix (CONTRIBUTING's small-bug route): keyboard reach should follow the panel's visible open state. There's no linked issue or prior maintainer sign-off.
Change
PreviewPanelShell: a closed, collapsible inline shell becomesinert. If focus is inside it at that moment, focus first moves to the existing Toggle right panel button. When the shell unmounts (after the animation, or straight away at 0 ms), the toggle remounts in the header; if that left focus on the page body, focus goes back to the toggle. Focus that is already outside the panel is not moved.PanelLayoutControls: the toggle gets adata-right-panel-togglehook so the shell can find it.Sheet, sidebar, embedded and non-collapsible inline panels are unchanged. An earlier revision also closed the Add panel surface menu on collapse. Main now does that itself (#15686), so that part and its tests were removed after merging main.

Hidden controls during the closing animation: the real client shows the closing shell with
inert=falsebefore andinert=trueafter. A single Tab from the composer reached the model picker in both revisions, because the panel comes later in tab order, so the real client did not show a Tab landing in the panel. The behavior test covers this case: with the panel collapsed, Tab into the scope skips its controls, and reopening makes them reachable again.Hidden controls during the closing animation: the real client shows the closing shell with
