I pushed a new helper class to inbound today to make it easier to work with

Thank you! I've been worried about these kinds of footguns for a
while. We could probably use something similar for JS...
RefPtr<DOMMozPromiseRequestHolder<GenericPromise>> holder =
new DOMMozPromiseRequestHolder<GenericPromise>(global);
Note, this can be written a bit more concisely as:
auto holder = MakeRefPtr<DOMMozPromiseRequestHolder<GenericPromise>>(global);
