I'm not seeing this behavior.
Can you see if this still occurs in a fresh profile (Profiles: Create a Temporary Profile)
If so, can you open the developer tools (Developer: toggle developer tools) and see if there are any errors in the console when you add a new cell.

Hi @amunger thanks for addressing this.

Unfortunately I can't repro it myself now either. The bug resolved after restarting VS Code and the Jupyter Kernel.

It does seem like unexpected behaviour so I'll keep an eye out for it again.

thanks for the update, I'll close for now
