Describe the bug

Hello. I have a .net9 blazor wasm PWA app. I had some issues w/ caching and saw that there was a FIX in .net10 for re-including the webmanfiest. So I went ahead and added that. However, upon deployment I'm getting a 404 error when deploying to IIS.

Upon inspection, I can see that the default web.config is lacking a <remove fileExtension=".webmanifest" /><mimeMap fileExtension=".webmanifest" mimeType="application/json" />

Adding this manually fixes the console error. But, wouldn't this mean that new .net10 wasm pwa blazor apps will face this same issue? It doesn't seem like there's a easy fix for this for .net9 besides adding a custom web.config. However, I'm not sure what I would be missing from the "default" web.config template since it's autogenerated.
