Select reviewer(s) search should clear after searching for a reviewer

Proposal

When creating / editing a merge request, it would be great if the "Search reviewer(s)" search input would clear and regain focus once a reviewer is selected. Currently, if I search for e.g. "Jane" and select a Jane, the search input still contains "Jane". That would only be helpful if all my coworkers were named Jane. It is far more common to want to type a new name each time.
