When checking native MacOS15 behavior, disabled PopupMenus still have shortcuts shown. Since the test doesn't modify the popup's shortcuts other than adding the shortcut for `A`, it makes sense that the result matches native behavior. So, I modified the test instructions instead to exclude MacOS from this step.
