• nsDocShellLoadState::SetupInheritingPrincipal() would be passed the value of nsDocShell::mItemType.
• This nsDocShell::mItemType is a private member of nsDocShell.
• nsDocShell::mItemType is only initialized with nsIDocShellTreeItem::typeContent or nsIDocShellTreeItem::typeChrome.

By these things, I suspect we can replace the type of nsDocShell::mItemType with BrowsingContext::Type safely, but there are some exceptions.

I seem we should add a getter function like nsDocShell::BrowsingContextType() conservatively, or wait to resolve other bugs to remove nsIDocShellTreeItem.
