Blazor AOT .Net6 Preview 7 - Still downloading Dlls

Describe the bug

I raised this issue previously, but I cannot find anywhere where it is being tracked to see status (apologies if I’m just missing it - happy to be linked to another ticket).

https://github.com/dotnet/aspnetcore/issues/33730

There are still a large amount of dlls being downloaded with AOT. Perhaps it is my misunderstanding of how it works but I do not expect the dlls, just a larger .wasm file?

Larger wasm file than before AOT:

But still a large number of dlls:

To Reproduce

Install workload: dotnet workload install wasm-tools

Project with RunAOTCompilation set to true.

<PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <ServiceWorkerAssetsManifest>service-worker-assets.js</ServiceWorkerAssetsManifest>
    <BlazorEnableTimeZoneSupport>false</BlazorEnableTimeZoneSupport>
    <BlazorWebAssemblyPreserveCollationData>false</BlazorWebAssemblyPreserveCollationData>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)'!='DEBUG'">
    <!-- Bug in .Net 6 Preview 7 - this should not be non-debug only. https://github.com/dotnet/runtime/issues/55750 -->
    <InvariantGlobalization>true</InvariantGlobalization>

    <RunAOTCompilation>true</RunAOTCompilation>
  </PropertyGroup>

Publish application.

The DLLs are still expected. Even with AOT compilation, there are scenarios where we need to fall back to using the interpreter with the .NET binaries. This increases the download size, but provides a more compatible .NET experience.

This is the main issue tracking AOT support in Blazor so should be reopened.
