### Describe the bug

Hotreload not working when applying rendermode InteractiveServer to razor page in .NET 8.0.100

### Expected Behavior

_Do you want to restart your app - Yes (y) / No (n) / Always (a) / Never (v)?_ message in terminal or working hotreload.

### Steps To Reproduce

1. Create new project with `dotnet new blazor`
2. Create new file **Test.razor** in Pages:

```
@page "/test"
@rendermode InteractiveServer
@inject IJSRuntime JSRuntime

Test

Test

HelloMessage

@code {
private async Task HelloMessage()
{
string text = new(await JSRuntime.InvokeAsync("alert", 123));
}
}
```

3. Run with `dotnet watch`
4. Try to click button. Gives js alert "123" as expected
5. Remove line `@rendermode InteractiveServer` and save
6. In terminal answer **Y** to _Do you want to restart your app - Yes (y) / No (n) / Always (a) / Never (v)?_
7. Try to click button. Nothing happens as expected
8. Restore line `@rendermode InteractiveServer` and save. This initiates message _File changed: .\Components\Pages\Test.razor. Hot reload of changes succeeded._ in terminal
9. Try button. Nothing happens. Expected: js alert "123". You may also try browser refresh F5, does not fix the problem.

Only fix is to stop and then run again with `dotnet watch`

Reproduce the behavior using a new `dotnet new blazor` project, `Test.razor`, and `dotnet watch`, following the listed render-mode changes and button checks. Start by tracing the hot reload handling for Razor pages and InteractiveServer changes; done means restoring `@rendermode InteractiveServer` after a reload leaves the button working without restarting the app.
