* fix VoiceOver bug for Listbox in Chrome
Chrome currently has a bug if you use a `Listbox` with a `Label` and use
the `aria-multiselectable` attribute. This combination will cause
VoiceOver to _not_ announce the `role="option"` elements when
interacting with them.
If we drop the `aria-multiselectable` OR the `aria-labelledby` it starts
working. Alternatively replacing `aria-labelledby` with `aria-label`
won't work either.
I filed a Chrome bug report about this here: https://bugs.chromium.org/p/chromium/issues/detail?id=1498261
---
Luckily there is a workaround in our `Listbox` implementation. Right now
we always require the `Listbox.Button` to be there. The
`Listbox.Options` component doesn't work on its own in our
implementation.
This means that whenever we open the `Listbox` that we have to go via
the `Listbox.Button`. This `Listbox.Button` is already labelled by the
`Listbox.Label` if there is one.
This also means that we can safely drop the `id` of the label inside the
`aria-labelledby` from the `Listbox.Options`.
This wouldn't have worked if our `Listbox.Options` could be used in a
standalone way without the `Listbox.Button`.
At the end of the day the hierarchy looks like this:
- Options is labelled by the Button
- Button is labelled by the Label
- Label
