The tap highlight is displayed when tapping a field that is already focussed. This bug is present on ToT. Reproduction steps 1. Navigate to https://developer.mozilla.org/en-US/docs/Web/HTML/Element/textarea 2. Tap on the search field to begin an input session - this correctly displays the tap highlight 3. Tap on the field again - the tap highlight is incorrectly shown
