Delete markdown cell and undo does not bring back the cell #119112
Description
Issue Type: Bug
- Open a github issue notebook in vscode repo
- Delete a markdown cell
- Undo
The cell doesn't come back visually. However if you save and then reload the window, it's actually saved to disk. It's just that after undo, the markdown cell doesn't restore its height (always 0).
