Is there an existing issue for this?

  • I have searched the existing issues

Describe the bug

I created a new Blazor-Wasm project from scratch with a linked RCL. If I now edit a component CSS within the Client folder Hot Reload will remove the styles from the linked RCL.
If I inspect the Client.styles.css file it will remove the @import line after every hot reload:

Thanks for reaching out. We think this issue is getting fixed in an upcoming VS release. If you still experience the problem in Visual Studio 17.12, please file a Visual Studio Feedback ticket.

@MackinnonBuck Well if you look at the video above you can see that this is not an Visual Studio issue. I'm using Visual Studio Code and used the command line to run dotnet watch run. So please reopen that issue.

I was able to reproduce this on the .NET 8 SDK, but it seems to have been fixed in .NET 9. @tmat, does this happen to ring a bell?
It also seems that this issue doesn't repro in VS (even when using the .NET 8 SDK), which makes me think this problem is specific to dotnet watch.
