    Description

      TapHandlers and MouseArea on android seems broken.

      If user tries to make many fast taps in MouseArea it just blocks without any error, and any input is not acceptable.

      If user tries to make many fast taps in TapHandler it gives errors on every tap: pointId (how much taps were made) is missing from current event, but was neither canceled nor released and blocks until user made same tap input again.

      On Linux same code works well, without any errors.

      Code examples:

      import QtQuick

Window {
    visible: true

    TapHandler {
    }
}

      import QtQuick

Window {
    visible: true
    
    TapHandler {
        id: additionalGestureMouseArea
                
        dragThreshold: 0
        
        exclusiveSignals: TapHandler.SingleTap | TapHandler.DoubleTap
        gesturePolicy: TapHandler.WithinBounds
        grabPermissions: PointHandler.ApprovesCancellation | PointerHandler.ApprovesTakeOverByItems | PointerHandler.ApprovesTakeOverByAnything       
    }
}
