macOS: some menu shortcuts are rendered incorrectly

In our software we use special actions with shortcuts < > ! = /

In Qt 5.9.7 these shortcuts were correctly rendered in the menu (except /, see sceenshot).

However, using Qt 5.15.2, all these shortcuts are rendered incorrectly (see screenshot).

The shortcuts work (are triggered) as expedted, only the display is wrong.

I have tried Qt::Key_Less insted of tr("<"), but it doesn't help.

Is there a work-around?

Please use source code Test1.zip to reproduce the problem.

Can it reproduce only on macOS, Win is ok.
