None opened. Follow-up of the shadcn audit on #579 (the DataTable Columns menu).

Description

Two menu keys behaved differently from shadcn (Base UI):

• Typeahead did nothing on items with an indicator (checkbox and radio items). labelOf() also read comment nodes, so with Rails' annotate_rendered_view_with_filenames the label became Before RubyUI::DropdownMenuItemIndicatorStatus and no prefix matched. It now reads only text nodes and elements, in DropdownMenu and ContextMenu.
• Tab with the menu open closed it and left focus on the trigger. Base UI moves on to the next control, and Shift+Tab stops on the trigger. close() already returns focus to the trigger, so Tab's default now runs from there; Shift+Tab is still prevented. The docs text and the controller header say so.

Testing instructions

• cd gem && bundle exec rake → 775 runs, 0 failures, StandardRB clean. cd mcp && bundle exec rake → 33 runs, 0 failures.
• /docs/data_table, Columns menu: ArrowDown to Reviewer, type s → focus on Status.
• Same menu: Tab → it closes and focus lands on the "Select all" checkbox; reopen, Shift+Tab → focus on Columns.
• /docs/context_menu: typeahead still moves through plain items.

Summary by cubic

Fixes two DropdownMenu and ContextMenu keyboard behaviors to match Base UI: typeahead now works on items with an indicator, and Tab moves focus past the trigger instead of leaving it on the trigger.

Changes

• Typeahead: labelOf() reads only text nodes and elements, so comment nodes from Rails' annotate_rendered_view_with_filenames no longer break prefix matching on checkbox and radio items.
• Tab: closing the menu returns focus to the trigger first, so Tab's default carries on to the next control; Shift+Tab is still prevented and stops on the trigger. The closing menu is kept inert while it animates out so focus doesn't land back inside it, and reopening clears that.

Updated the docs text and the controller header comment to describe the new Tab behavior.
