VSCode Web include does not work

I was testing VSCode Web with asciidoc and using Github Repositories.

When trying to include local file it says: include file not readable

index.adoc content: include::snippet.adoc

snippet.adoc content: :somedefinition: true

I would expect it to include the file. I tried also include::./snippet.adoc and some variants of absolute path.

Is this not possible using GitHub Repositories which uses Virtual Workspaces feature?
