  WindowEventLoop can infinite loop trying to run idle callback in suspended pages

WindowEventLoop::didReachTimeToRun schedules itself again when an idle callback is
scheduled but we didn't have enough time to run it. This logic can infinite loop
when the timer never fires because the document has been suspended.
