Formatting is broken on VS Code window reload

[JRiggles]

Running the VS Code command Developer: Reload Window causes *.hdnb notebooks to lose their existing formatting and to treat every line in the *.hdnb file as a separate Markdown cell. Opening the *.hdnb in Notepad shows that the file contents are unmodified, so I suspect this is an issue with how the file is parsed within VS Code.

Environment:
VS Code 1.68
Windows 10 Pro

Additional info: This also happens when closing and re-opening VS Code. And I've figured out that its related to having code strings (strings surrounded by backticks) in Markdown cells! Opening the *.hdnb file in Notepad and removing inline backticks fixes the issue. Also, I was wrong about the file being unmodified: code blocks need to have their language specifiers added again since those seem to get removed, which is best accomplished in Notepad (or similar)
