Nika Layzell e1e439a7b1 Bug 1769619 - Introduce nsIDocShellTreeOwner::primaryContentBrowsingContext, r=smaug
This is currently effectively just a helper around the existing
properties. Theoretically we could streamline things here in the future
by managing primary content entirely based on BrowsingContext rather
than docshell, but there's enough complexity there right now with other
properties like updating properties on content shells as they're
attached, that it's probably not worth trying to unify right now,
especially considering the low number of consumers.
