* add `get-text-value` helper
* use `getTextValue` in `Listbox` component
* use `getTextValue` in `Menu` component
* update changelog
* ensure we handle multiple values for `aria-labelledby`
* hoist regex
* drop child nodes instead of replacing its innerText
This makes it a bit slower but also more correct. We can use a cache on
another level to ensure that we are not creating useless work.
* add `useTextValue` to improve performance of `getTextValue`
This will add a cache and only if the `innerText` changes, only then
will we calculate the new text value.
* use better `useTextValue` hook
