--- Comment #6 from Chris Dumez <cdumez at apple.com> ---
Should be coordinated with Alex because I think he is in the process of refactoring this code (and fixing this at the same time) I believe.

That said, a trivial fix would be to replace WTFMove(formState), std::exchange(formState, nullptr). It is equivalent given our current implementation of the RefPtr<> move constructor but looks safer.
