ThreadLockedRawWindowHandle isn't actually thread locked?

[ItsSunnyMonster]

I was reading the code of bevy_window and found a struct called ThreadLockedRawWindowHandleWrapper (TLRWHW) which is a wrapper around the RawHandleWrapper struct. In the doc string, it says that a TLRWHW is a RawHandleWrapper that cannot be sent across threads, but there isn't actually anything preventing that from happening. In fact, because the TLRWHW is used in create_surface, it has to be Send and Sync. Is this normal? Or is it an issue that should be fixed?
