Syntax highlighting incorrect for methods with type hinting for complex return.

[bedge]

VS Code version: Version 1.28.0-insider (1.28.0-insider)
vsc python Extension version: 2018.8.0
vsc magicpython Extension version: 1.0.12
OS and version: MacOS High Sierra 10.13.6 (17G65)
Python version (& distribution if applicable, e.g. Anaconda): Virtualenv 3.6
Type of virtual environment used (N/A | venv | virtualenv | conda | ...): virtualenv

Expected behavior
get_args method comment, and string should be formatted as they are in get_args_no_hints

Similar after installing Chromodynamics theme:

Steps to reproduce:
Add type hints to method. The return value of anything other than a simple scalar causes this.

This is highlighted with MagicPython (correctly):

def get_args(arglist: List[str]) -> Dict[str, str]:
    """
    comment
    """
    return args  

What does the bottom-right corner of the status bar say?

Nothing relevant. I have many extensions loaded, so there's a lot of status bits from many places.
I checked the extension logs and didn't see anything interesting, even when I added/removed the return type annotation and the highlighting toggled from bad/good.
Restarting with all extensions disabled the highlighting is correct. I guess I'll disable one at a time to see what's causing this.
I'll report back.

It's the "Python for VSCode" plugin that's causing it. I opened a new issue there: tht13/Python-vscode#27
