QMenu (popup) does not accept mouse clicks on Mac OS (works fine with 5.6)

It is impossible to trigger action by clicking on QMenu shown as popup, regardless how the popup is triggered (i.e. it does not even work when QTextEdit is right-clicked).
For example:

• right click on QTextEdit (with some text in it)
• can't trigger any action by mouse click (Select All, Undo etc.)
• CAN trigger any action by using cursor keys (up/down arrows) and hitting Enter or Space

Everything works perfectly fine when compiled with Qt 5.6, it also works fine with Qt 5.7.0 Beta on Win7
This can be easily reproduce from following example project:
~/Qt5.7.0/Examples/Qt-5.7/qtbase/widgets/mainwindows/application/application.pro
