I guess this is happening because of the note in the
NSEvent locationInWindow method docs that the event
can have a nil window, in which case it gives you the
event location in screen coordinates:
https://developer.apple.com/documentation/appkit/nsevent/1529068-locationinwindow

Those docs also say that the common way to deal with this
is to use the NSView convert method to get the window-relative
coordinates that you want. Maybe we just need to do that?
