Describe the bug

Hot reload doesn't work for Blazor WASM

after changing the file, I see a message "watch : File changed: ...." and nothing happens after. If manually reload the browser page also no changes.
Also I can't close the app by Ctrl + C. I see a message " Application is shutting down..." and that's all. The app freezes until close terminal.

Hosted Blazor app, ASP.NET app - they don't have this issue. Only WASM Blazor has this problem.

To Reproduce

.NET 6 preview 3+ ( with "hotReloadProfile": "blazorwasm", for preview 5 - without)
Create new blazor wasm project and run with:
dotnet watch
