If I click to close a menu popup, like after clicking File, Edit, View, etc., clicking a third time does not open the popup again. It re-opens on the 4th click instead of the 3rd.

This can be reproduced with the opengl\legacy\grabber example. If commented out glWidgetArea->setWidget(glWidget); menu works fine.

This works in 5.1.1 but not anymore in 5.2.1.

Here is the first bad commit:
