Kris Maglione c01ad83372 Bug 1571502: Don't leak TabGroups which have never had windows joined to them. r=nika ... Currently, TabGroups know to break their reference cycles only when the last window leaves them. For TabGroups which have never had a window join (which happens under Fission), this means they also never see a window leave, and therefore never break their reference cycles, and leak. This patch adds a check to break reference cycles if no windows have joined by the time a BrowserChild they belong to is destroyed. MANUAL PUSH: Lando fails to rebase.
