Menu block doesn't seem to follow active trail

Have you tried the latest patch from 🐛 Starting level deeper than 1 ignores active trail, when "Expand all items" is enabled Needs work ? That also deals with showing menu branches 2+ levels down, but focuses on the "expand all items" setting and not individual nodes' settings. I'm curious if the logic added by that patch solves your problem too.

Also note that the recently released version 2.0.3/3.0.3 resolved 🐛 Active trail is cached incorrectly Fixed which deals with active trail, so check to see if that helped your problem too, even without the patch.
