If the pref browser.fission.simulate is true, the event dispatcher in ActorManagerChild will not dispatch events to actors that aren't associated with the same window as the event's target. In addition, when that pref is on, the actors associated with sub-frames will have their content property bound to the correct content window, that might differ from the message manager's window (which is always related to the top level). Then, in order to write Fission-compatible code, that specific actor will need to be declared with allFrames = true, meaning that it wants to be instantiated for every frame, and not just top-level ones Differential Revision: https://phabricator.services.mozilla.com/D6358 --HG-- extra : moz-landing-system : lando
