Describe the bug

Starting with version 7.0.10 of Microsoft.AspNetCore.Components.WebAssembly.DevServer we are no longer able to debug Blazor code that is running inside an Angular application with a remote debugger. The file:// "folder" is no longer being shown in the Chrome sources tab and this seems to be happening because of the following error message:

info: Microsoft.Hosting.Lifetime[14]
      Now listening on: http://localhost:4201
info: Microsoft.Hosting.Lifetime[0]
      Application started. Press Ctrl+C to shut down.
info: Microsoft.Hosting.Lifetime[0]
      Hosting environment: Development
info: Microsoft.Hosting.Lifetime[0]
      Content root path: C:\MyProject
[09:23:45] fail: DevToolsProxy[0]
      Failed to load https://localhost:4200/_framework/Microsoft.AspNetCore.Authorization.dll (The SSL
 connection could not be established, see inner exception.)

We are launching Chrome 117.0.5938.132 with the the following options: --remote-debugging-port=9222 --allow-insecure-localhost --incognito https://localhost:4200/. Our application uses an untrusted certificate and that is probably the message in the inner exception.

Changing the application to use http results in the following error message:

Failed to load http://localhost:4200/_framework/Microsoft.AspNetCore.Authorization.dll (Response status 
code does not indicate success: 404 (Not Found).)

This is happening because we start Blazor with the following options:

await Blazor.start({
    loadBootResource: function (type: string, name: string, defaultUri: string, integrity: string) {
        return `${defaultUri.replace("_framework", "assets/dotnet")}?${integrity}`;
    }
});

But the new version of the DevServer no longer seems to know about this and uses the wrong _framework url.

Downgrading both Microsoft.AspNetCore.Components.WebAssembly and Microsoft.AspNetCore.Components.WebAssembly.DevServer to version 7.0.9 resolves the issue and allows us to debug our application. I tried to check the changes between those two versions here and in the dotnet/runtime repository but I was unable to find a commit that was causing this.

@thaystg should I move to the runtime repo? Looks like there was some regression in the 7.0.10 that needs to be reviewed.

[thaystg]

Yes, please.
