🐛 Bug Report

When navigating to a certain page which is nested underneith a FluentNavGroup the correct item will get the active class but the FluentNavGroup will be collapsed by default. This is really annoying when you come from bookmarks or external links to your website.

Please see this video for a demonstration:

We have no notion of a 'parent/child' relationship in the current NavMenu. I don't see a way how we could do this at the moment.
Any ideas?

Closing this as we do not have a solution for this for the foreseeable future
