Comment 5 for bug 1380702

Taking a look at this now. I reproduced it with multiple Qt5 applications - first step now is to triage which exact component is responsible. appmenu-qt5 doesn't do much by itself, as it's only a QPA platformtheme plugin that takes the window's QMenu's and exports it through DBus. Need to check what Qt does when it actually has a platformtheme loaded and a platformmenu defined - maybe in this case dealing with shortcuts is also left for the theme's implementation? We'll see.
