What's Wrong?

Describe the bug

The cmd+escape keybinding toggles focus between the active editor and the Claude Code panel correctly when the text input is active. However, when an AskUserQuestion prompt is displayed (single-select or multi-select), using cmd+escape to switch to the editor and back does not restore focus to the prompt options. The behavior differs between prompt types.

Single-select behavior

• Focus returns to the panel but lands on a non-interactive element (pressing Space/Enter does nothing)
• Tab order: panel title → close button → first option (3 presses to reach options)
• Shift+Tab navigates backward through earlier conversation elements
• Scroll position has no effect

Multi-select behavior

• Focus does not return to the panel at all — Tab moves into other parts of the VSCode interface
• Shift+Tab works and navigates the options in reverse order (bottom to top)

What Should Happen?

Focus returns to the prompt options and keyboard navigation works, consistent with how focus returns to the text input in normal conversation.

Additional Information

Possibly related to #28722 (AskUserQuestion focus management). That issue covers focus being stolen by the prompt; this is the inverse — focus cannot correctly return to the prompt via the standard toggle.
