The details

Resolves

Fixes #10635

Proposed Changes

Replace the toolbox/workspace flyout if/else with targetWorkspace.hideComponents(false) so other registered components can close their flyouts too.

Reason for Changes

#9610 removed the block-creation call to hideChaff(), which called hideComponents(false). This restores that same call through focus handling, extending #10506 to trashcan, backpack, and custom flyouts such as App Inventor parameter flydowns.

Test Coverage

• Flyout
  • focus management
    • toolbox
      • Losing flyout focus hides autoclosing flyout and clears category
      • Losing flyout focus preserves non-autoclosing flyout and category
    • workspace
      • Losing focus hides autoclosing flyout
      • Losing focus does not hide non-autoclosing flyout
    • other
      • Losing focus hides autoclosing flyout
      • Losing focus does not hide non-autoclosing flyout

The other tests represent flyouts such as trashcan, backpack, and custom flyouts, including App Inventor parameter flydowns.
