Expected behaviour

LaTeX being rendered, as it does in Jupyter Notebook, Jupyter Lab, Google Colab and any other NBViewer.

Python: Julia:

Actual behaviour

Markdown cells outputs raw LaTeX, code cells output says "No renderer could be found for MIME type: text/latex":

(The same code above, but in VSCode): Python: Julia:

Steps to reproduce:

1. Install Jupyter with any Kernel;
2. Install VS Code Insiders;
3. Install Jupyter Extension;
4. Create and open a new notebook (or open an existing, whatever);
5. Select any kernel you want;
6. Try writing the fanciest equation with LaTeX math;
7. Cry.

Yes, with Code-Insiders, even single dollar-sign Latex between $ $ , does not work in the new version notebooks markdown using the Jupyter extension.
