fix(documents): match the filter triggers to the search field's height

The facet triggers and the clear control were 32 px beside a 44/40 px
search field, below the phone tap floor. They now share its height and
reach 44 px square on a phone, and the browser's own clear button no
longer sits on the search icon when the field shrinks.
