Unfortunately, this isn't really how things work. Either a widget asks
to capture input, in which case it can get events outside its
boundaries, or it doesn't.

If a widget does ask to capture events outside its boundaries, it then
needs to have some idea about what to do with them.

And that's hard (and each group will implement it differently, but
poorly)....
