--- Comment #12 from PhistucK <phistuck at chromium.org> ---
This is the apparent failure -
FAIL Returning false must not cancel the event, because it's coerced to the DOMString "false" which does not cancel CustomEvents: CustomEvent, cancelable assert_false: The event must not have been canceled expected false got true

Huh, why would it affect a CustomEvent of type "beforeunload"?
This code path is only reached if is<BeforeUnloadEvent>(event)...
