Hot reload doesn't refresh the page in a Blazor Web App

[danroth27]

Repro steps:

• Create a new Blazor Web App with .NET 8 Preview 6
• Run the app (with or without debugging, doesn't matter)
• Make a change to Index.razor and apply the change to the running app

Expected result: Change applies successfully and the UI updates with the change.
Actual result: Change applies successfully, but the UI doesn't update. You have to manually refresh the page.

It looks like the change does apply, but server-side rendered pages don't refresh automatically. Interactive pages, like the counter page, seem to update fine.

This is the same as #47026.

I'll track progress in that issue but use this one to validate once the change is in. 🙇🏽
