Hot reload not working on .cshtml (converted project) - Workound found but unsure why it's needed

[dotnetshadow]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

I recently updated my asp.net core project from .net 5 to .net 6

Everything in hot reload seems to work fine except for .cshtml files.
I've gone through all the issues associated such as response caching etc

Workaround
I was finally able to get hot reloading working for .cshtml by enabling the following in my .csproj

<ItemGroup>
	  <!-- extends watching group to include *.cshtml files -->
	  <Watch Include="**\*.cshtml" Exclude="node_modules\**\*;**\*.js.map;obj\**\*;bin\**\*" />
  </ItemGroup>

I wonder why the above is necessary?

Interestingly enough if I create a new project I don't need to do the above, so I'm just wondering what I can do about it?

Edit
I just tested on a new project and added runtimecompilation package and indeed .cshtml files stopped working
So it seems there is an issue here?
xml <PackageReference Include="Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation" Version="6.0.1" />

Expected Behavior

Hot reload should work on .cshtml files

Steps To Reproduce

I would provide a repo if there is a need to

Exceptions (if any)
