CmdPal: Restore correct focus behavior in Extensions settings page #46643
Description
Description of the new feature / enhancement
Focus management in the Command Palette Extensions settings page should preserve user context when navigating with the keyboard.
When a user navigates through the extensions list and then leaves it, returning via Shift or Shift+Tab should restore focus to the previously selected extension card. Currently, focus may jump to the first or last item, which breaks navigation continuity.
This issue tracks re-implementation of a previously reverted change that attempted to address this behavior.
Previously implemented by #45903, but that has unintended side-effects.
Scenario when this would be used?
Keyboard-only and assistive technology users can lose context due to unexpected focus movement. This increases navigation effort and reduces usability of the Extensions page.
