Pull request overview
This pull request adds accessibility support for screen readers by introducing the aria-multiselectable="true" attribute to the List widget when it's in multi-select mode (selectionMode is 'multiple' or 'all'). This helps screen readers properly announce that multiple items can be selected in the list.
Changes:
- Added
_isMultiSelectMode()helper method to check if the List is in multiple/all selection mode - Updated
_setListAria()and_setGroupBodyAria()to conditionally set aria-multiselectable attribute - Added test coverage for both regular lists and collapsible groups with different selection modes
- Updated Jest snapshots to reflect the new aria attribute in header filter tests
