macOS: QGuiApplication::mouseButtons() always returns NoButton after window resize

On Mac os, If window is resized and mouseButton() is queried it always returns NoButton. Same thing works fine on other platform.
Attached is simple example which can be used to reproduced this problem. Very same example works on Windows.
Steps: run the example and using mouse resize window, drawn line will change its color. that means mouseButton() works, on Mac this does not change the color because mouseButton() return noButton.
