Hot Reload does not work when running dotnet blazorwasm app in container

[SnoCold]

Hey All, just wanted to ask if this is a known issue or I am doing something wrong as there are not enough resources online.

Here is my Dockerfile

ARG REPO=mcr.microsoft.com/dotnet/aspnet
FROM $REPO:6.0.0-preview.7-focal-amd64

ENV \
  # Unset ASPNETCORE_URLS from aspnet base image
  ASPNETCORE_URLS=http://+:80 \
  # Do not generate certificate

  # Do not show first run text
  DOTNET_NOLOGO=true \
  # SDK version
  DOTNET_SDK_VERSION=6.0.100-preview.7.21379.14 \
  # Enable correct mode for dotnet watch (only mode supported in a container)
  DOTNET_USE_POLLING_FILE_WATCHER=true \
  # Unset Logging__Console__FormatterName from aspnet base image
  Logging__Console__FormatterName= \
  # Skip extraction of XML docs - generally not useful within an image/container - helps performance
  NUGET_XMLDOC_MODE=skip \
  # PowerShell telemetry for docker image usage

I also added the "hotReloadProfile" : "blazorwasm" in launchSettings.json, so I get the "Hot Reloading is Enabled" message

I am using the Vscode Remote Container development feature to open a folder in a container. (Default Settings) created app using

dotnet new blazorwasm -o MyApp
cd MyApp
dotnet restore
dotnet watch run

Steps:

Try changing a CSS file

Expected:

Change reflected in UI

Actual:

no change is seen in the web app, not even after refreshing the page

Edit: Code changes in Razor pages work, but css modifications don't reflect even though this message is printed

File changed: /workspaces/Project/Maybe/Shared/MainLayout.razor.css.
watch : Hot reload of scoped css succeeded.
