Hmm, that is surprising. I'm able to reproduce the issue with your app, but not with a vanilla Blazor app without MudBlazor. @Garderoben Is it possible that something in MudBlazor is triggering an extra render on navigation?

I removed all the references to MudBlazor from that repo and the issue still occurs. I can update the repo if you'd like...

Yes, updating the repro to remove MudBlazor would be great. I wasn't able to repro the issue when I tried this myself.
