All issues have been resolved. The code cleanly handles Escape key interactions and the search index registration approach has been refactored to use context-based registration. Latest test fixes add necessary mocks for the new search components.

• Escape key handler unreachable when no results - users cannot close dropdown with Escape when "No results found" is displayed
• Duplicate Escape key handler code at lines 77-82 is now unreachable dead code

The search functionality implementation looks good overall. One cleanup item remains.

• Escape key handler unreachable when no results - users cannot close dropdown with Escape when "No results found" is displayed
• Duplicate Escape key handler code at lines 77-82 is unreachable dead code and should be removed
