Describe the bug

I have a blazor Wasm hosted project.

Environnements are not working as expected:

Queries contains Blazor environment header : blazor-environment: Development
but appsettings files are not loading accordingly. Only base appsettings file is loading.

I have to force environnement with

    <script>
        Blazor.start({
            environment: "Development"
        });
    </script>

to have my appsettings files loading correctly.

Although I tried to display Environment in my web page.
When the environnement is forced by Startup script I see Development, so it's fine.
But When I let blazor-environment header determine the environment, I see Development, Development

I noticed something weird with
blazor.webassembly.js:

blazor.boot.json

and donet.js

It should be the explanation of the issue.
