handler for "global click filtered by whether click target is outside
of search view" executed after prop deletion handler has executed =>
the whole proposition has already been removed from the document and
thus isn't a descendent of the searchview anymore => test matches and
drawer closes.
Altered handler to stop propagation so does not reach global handler.
