      # Note: These are disabled because of a circular dependency between this
      # repository and Python shinylive package (which is in the py-shinylive
      # repository). This set of tests does a `pip install shinylive`, but that
      # package depends on this repo, and can only be updated after a release is
      # made from this repo. But if these tests fail, it will block this repo
      # from making a release. To fix this, we will probably need to avoid
      # installing the Python package.
