- TagEditor test renders full AutocompleteList for end to end a11y test
- AutocompleteList now uses a `is-hidden` class rather than preact to hide itself. This was necessary to pass a11y lint.
- Change TagEditor to unset the activeIndex when adding tag
- Add `aria-label` to TagEditor <input> filed, `placeholder` attr not sufficient for lint
- Very slight color adjust on $grey-5 to keep 4.5:1 contrast spec
