Description

Since .NET 8 preview 7, the whole layout would refresh when a navigating to another page, prompting the "Loading..." each time.

Steps to Reproduce

  1. Create new MAUI Blazor Hybrid project in .net 8 preview 7.
  2. Navigate back and forth between counter and home page.
  3. Observe "Loading..." appearing /flashing after each nagivation.

In previous version, the container / MainLayout.razor would not re-render, just the children components that change.

This gets more severe/noticeable the longer a component takes to load, because the MainLayout is disappearing/re-appearing.

This is a symptom of this issue: #16609

Can you try the workaround at #16609 (comment) and let us know if that fixes it?
