I think this may be a bug...

[jgarte]

def cat(x: str) -> str:
    """
    Args:
        x: (meow) # Try executing `meow-block` on (meow) to select the matching parens.

    Returns:
        meow
    """
    return {"meow": x}  # type: ignore

The above should be executed in python-mode. For example, in a file called hello.py.
