QQuickView inside widget via createWindowContainer not resized before mouse enters QQuickItem

Attached project integrates a QQuickView into a Cocoa application using a QMacNativeWidget.

when resizing the NSWindow, the QQuickView is not redrawn correctly.

1. resize the window via the mouse (the QQV is not updated, compare: before_mouse_on_qqv.png)
2. move the mouse cursor to the QQV (the QQV is still not updated, compare: before_mouse_on_qqv.png)
3. move the mouse to the position where the Button is supposed to be (the QQV is updated, compare: after_mouse_on_qqv.png)

expected behaviour: the QQV is updated when resizing the window changes the position of the QQV.
