Examples: https://a11y-guidelines.orange.com/en/web/components-examples/listbox-with-checkboxes/ http://whatsock.com/Templates/Listboxes/Checkable/index.htm Expected behavior: When swiping between the available options of a listbox, both the select state and the checked state (when true) should be conveyed. The same should occur when tapping on an option to change the checked state of that option. Sincerely, Bryan Garaventa 1781793 1 webkit-bug-importer 2021-08-03 17:27:50 -0700 <rdar://problem/81489186>
