theme: fix fileselector search button layout

Summary:
to correctly (and quickly) calculate part geometry when setting a part relative
to another part, align must be set on the axis that is relative to another part.
also since the height on this part should not be changing, set fixed on the
vertical axis to optimize geometry calcs
