Description

### Is there an existing issue for this?

- [X] I have searched the existing issues

### Describe the bug

UK Gov only allows javascript as an experience enhancement. All sites must work on browsers with JS disabled.

If I disable JS and run the new Blazor web app "Weather" page I just get an endless `Loading...` message.

To fix this I have to remove `@attribute [StreamRendering(true)]`, but then I cannot make use of StreamRendering in the majority of browsers that have JS enabled.

Could this please be fixed to have a fallback, so `StreamRendering` is only active if `true` and JS is enabled?

### Expected Behavior

Running a `StreamRendering(true)` decorated page should not stop the page working in a browser with JS disabled.

### Steps To Reproduce

1: New Blazor web app
2: Include the sample pages
3: Disable JS in the browser
4: Run the app

### Exceptions (if any)

_No response_

### .NET Version

8.0.100-rc.2.23502.2

### Anything else?

_No response_
