Thanks for reporting this. I have verified this behavior, and I'm not quite sure how to fix it just yet.

I have found a potential "fix" for this, but I'm not really happy with it. Why does MAUI make custom navigation such a pain?

I'm going to keep trying different things before committing my hack.

I have been suffering a lot with MAUI also so I really appreciate the effort 😅
