From bug 13341: we fire a fake mousemove event when a modifier key is pressed. We shouldn't. Currently, it's needed to cause things like the status bar message to update.

Is there a workaround for this bug? Is there a way to disambiguate fake mousemove events from real ones, does one of the event properties identifies this as a modifier type mousemove?

In WebKit2 this comes out of this code: m_flagsChangedEventMonitor = [NSEvent addLocalMonitorForEventsMatchingMask:NSEventMaskFlagsChanged handler:[weakThis] (NSEvent *flagsChangedEvent) { if (weakThis) weakThis->postFakeMouseMovedEventForFlagsChangedEvent(flagsChangedEvent); return flagsChangedEvent; }];
