DoubleClick Event on Qt wayland

[flowery]

I am running an application on qt wayland.In that I am handling double click event on on window which is smaller in size .Lets say 100x100 displaying on top of 800x800 .When I do first click on outside the window and second click on inside window ,it is receiving as double click event by the smaller window.The mouse area is defined only for the smaller window,But I qt catches first click event from the mouse area defined in the larger window and second click from the smaller window irrespective of the postions and Item.MouseEventSource is Qt::MouseEventSynthesizedByQt. Is it existing bug in Qt.I am using Qt 5.11.2.
