Bug 1656854 - Part 2: Add a BrowsingContextGroup keepalive to BrowserParent shutdown, r=farre In bug 1652085, I added BrowsingContextGroup keepalives while waiting for replies to the discard message, however that message isn't actually sent to the current owner process. Instead, the BrowsingContext is discarded by the PBrowser being destroyed. This should help ensure we also keep the group alive during normal BrowserParent destruction. Differential Revision:
