Reviewed by Matthew Finkel.
319079@main normalizes an empty document URL to about:blank in
NavigationRequester::from so
about:blank inherits its initiator's policy container rather than a
cross-origin one. That also
makes NavigationAction::isEmpty() false for a history restore in a relaunched
process, so its
triggering action is preserved and the navigation reports
NavigationType::BackForward.
handleBackForwardNavigation then runs for a reload, whose navigation sets
reloadItem() rather
than targetItem(), so the prior state reads as Disabled and Enhanced Security
goes dormant. The
resulting process swap discards the HTTP fallback state and the reload is
upgraded back to https.
Fix by falling back to reloadItem() when there is no targetItem(). Both name
the item being
navigated to and only one is ever set, so the item's stored Enhanced Security
state is used
instead of defaulting to Disabled.
