LGTM

Btw, are there any ways of writing a test for these behavioral changes? If not,
that's fine, but I just wanted to put you on the spot to assert that it's not
possible to do so, or to write a test :)

I tried writing a test for this. But looks like right now, it is not possible to
generate synthetic XI2.x events using XSendEvent (the fix is for XI2.x events.
The old code works OK for XI1.x events)
