That shouldn’t be required. The app passes the menu structure to the os, and there’s where the rectangle coordinates are determined, as well as handling that layer of mouse events.
If the language is Farsi, the os will build the menu columns right-to-left, and the app shouldn’t know or care. The app gets a File Open event, not a mouse click x,y event.
That might be safest if there are too many special cases to account for (test).
