[Wayland] No Icon for menu in window bar

Hi,
After a time I tried to give Wayland a chance again, but noticed that the menu icon does not appear in the window bar of GTK+ apps (e.g. DBeaver, Handbrake).
Under X11 everything is as it should be.
The problem exists with different themes/window decorations.
Is this a known bug?
Any hints how to resolve the problem?
