By passing a weak reference back to the DocumentChannelParent into DocumentLoadListener for object loads, we are able to handle process switching loads by asking the content process to create a BrowsingContext, and delaying the real process switch until it becomes available. The load then completes as it would before, acting as a normal process-switching subframe load. Differential Revision: https://phabricator.services.mozilla.com/D86580
