Generally this is expected behaviour for usages of focused text boxes (ie. to clear search content), but not so much here. Addresses https://github.com/ppy/osu/discussions/19403#discussioncomment-3230395.
Seemingly harmless schedule delay ommission meant that the textbox may not be in a state it can handle the incoming focus event. Regressed in https://github.com/ppy/osu/pull/14345#discussion_r690697501.
Closes https://github.com/ppy/osu/issues/14684.
