drawin_apply_moveresize() calls client_ignore_enterleave_events() internally,
because it also wants these to be ignored. This means that the code disables
enter/leave events twice and then enables them twice. This recursive disabling
is something that should not occur.
Fix this by having drawin_map() disable the events a bit later.
