fixup! Bug 27476: Implement about:torconnect captive portal within Tor Browser

Bug 41816: Workaround to fix the top navigation

Using the top navigation does not always work as expected, because we
pass a null connection state, instead of the actual state.
We could start storing the state as a member, however further refactors
are planned (see #41710), so also directly asking the parent
for the current state works as a quick&dirty workaround.
