I have modified the PR to move the icon w.r.t bullet skin width and it looks like this in windows 11..I believe this should work for windows 10 also but I dont have windows10 to check

I dont think we can tamper with text location as it is done in WindowsMenuItemUI#paintText which does not have any knowledge of bullet/icon presence.
Also, ideally I dont think this should be applicable for windows10 and we should do this only for windows11 but I am not sure if there is version check in our code and anyway, windows10 would be EOL-ed and unsupported platform in few months
