[WPE][GTK] preventDefault() on pointerdown does not suppress gesture-based
compatibility mouse events from touch.
https://bugs.webkit.org/show_bug.cgi?id=311544
Reviewed by Carlos Garcia Campos.
After dispatching pointer events via dispatchEventForTouchAtIndex() in
EventHandler::handleTouchEvent(), check
preventsCompatibilityMouseEventsForIdentifier()
for the touch pointer ID. If it returns true (meaning pointerdown was
cancelled),
set swallowedEvent=true so that wasEventHandled=true propagates to the
UIProcess,
preventing gesture-based mouse synthesis.
