arabic text shapes incorrectly when using accelerator

I think this bug has happend before in the 5.x series, the screenshot will explain everything (please don't care about theme, i use a windows-like window decoration, I am using Qt6 under Linux/X11)

in the sample screenshot, i was trying to use accelerator with arabic text in menubutton and button, i think it is duplicate of QTBUG-49861 but not sure.
