What

Restore the chat prompt caret when returning to VS Code if the prompt was focused before the window was deactivated (sidebar and Open in Tab).

Fixes #14139

Why

Alt-Tab (or any OS window switch) blurs the webview textarea. VS Code restores workbench focus to the webview, but not the inner input, so keystrokes are lost. Cursor already restores this correctly.

How

• Remember whether the prompt held focus, without treating Alt-Tab blur as “user left the chat”
• When the webview is focused again, focus the textarea once
• After VS Code settles, send a single restoreInput if needed; only show()/reveal() the host if the webview never got focus
• Do not steal focus from the editor, other text controls, popups, or Agent Manager terminals

Tests

• Unit tests for the host latch and webview hold
• Manual: focus the prompt, Alt-Tab away and back — typing goes to the prompt; focusing the editor first does not steal back to the prompt

I can't reproduce, seems to be only os specific.

Thanks for the fix and for the clear write-up on the OS focus behavior. I merged main into the branch to clear the conflicts in PromptInput.tsx and focus.ts, keeping both createHold and hasTextSelection. Enabling auto-merge now.
