Comment (by dd32):

 I don't think linking to external resources has ever been "supported" by
 `add_menu_page()`, but it certainly does work, if only because we don't
 explicitly prevent urls. Have you found any documentation referencing the
 support anywhere by any chance?

 While we could scatter a few `is_url()` like function calls throughout the
 menu generation, I'm not sure it's worth actually supporting myself.
