* ensure that `aria-selected` is explicitly set to `false`
The WAI-ARIA Best Practices don't recommend this and prefer
`aria-selected: true` or undefined (aka not existing when it is
"false"). However in practice, both MacOS VoiceOver and NVDA experience
strange issues if you don't do this (e.g.: everything before the
selected item is also selected)
* update tests to ensure we are checking for `aria-selected=false`
* update changelog
