This makes various changes to the named lookup/navigation code to make them more precise, and avoid issues which could happen if a window is closed while script is still executing. This also should improve handling for inactive windows in some cases, by more frequently working off of the WindowContext tree rather than the BrowsingContext tree. As part of these changes, some behaviour was changed around e.g. the file URI exception to avoid the deprecated nsIPrincipal::GetURI method. I don't believe the behaviour should have changed in a meaningful way. Differential Revision: https://phabricator.services.mozilla.com/D171755
