"Toggle Line Comment" (aka: cmd + /) Not Working

Ninguém assumiu esta issue ainda.

* **Editor name and version**: VSCode v1.55.0
* **Platform**:
* **Color scheme**: default
* **MagicPython version**: v1.1.0
* **A sreenshot**:
* **5-10 lines of surrounding code**:


The issue I'm having is simple. I was using `Python` for VSCode without any issues but then started having code-coloring issues when using typings. I then installed "Python Extension Pack" (see below) which includes `MagicPython`, and when I try to run "cmd + /" or manually execute the command with "> Toggle Line Comment" it doesn't do anything.

I checked the keyboard shortcut and there is no conflicting shortcut as well as the keyboard shortcut is set correctly.

Reproduce the failure in VSCode v1.55.0 with MagicPython v1.1.0 and the listed Python Extension Pack installed, using both cmd + / and the Toggle Line Comment command. Check how MagicPython declares Python comments and how VSCode selects the active language mode. Done means line comments toggle normally without a shortcut conflict.
