Expected behaviour

I do not expect the presence of the Microsoft Python extension to interfere with the ability of other extensions to show Jupyter Notebook previews.

Actual behaviour

The presence of the Microsoft Python extension to interferes with the ability of other extensions to show Jupyter Notebook previews in VS Code. ( See jithurjacob/vscode-nbpreviewer#13 (comment) )

Steps to reproduce:

1. Install the Microsoft Python extension.
2. Install the VS Code Jupyter Notebook Previewer v1.1.0 by @jithurjacob .
3. Open a Jupyter notebook. The preview button will not appear. It will appear if the Microsoft Python extension is removed and VS Code is reloaded.
