I think it would be more "obviously correct" if we switched to
(window-buffer (posn-window (event-end click))) instead.

Same here.

I'm not sure what to think of this because I don't understand
its motivation.  IOW at the very least it should come with a comment
explaining why we need to ignore `ignore`.
