As a toolkit guy, this is a "no-no". Things like implicit grab tracking
rely on some coherence from the windowing system, and many button
handlers highly count on just receiving 1 event pair per button. unless
toolkits have per-button counters and keep track of this themselves
(they don't), multiple presses & releases on the same button is going to
confuse toolkits and apps big time.
