it is as if i cannot undo the changes that have been saved by cmd-s or autosave

[misha-antonenko]

is there a quick (and possibly ugly) remedy for this? it becomes too easy to throw away work in such conditions

[DonJayamanne]

@DonJayamanne

1. open a remote Jupyter notebook with a remote kernel
2. make some modifications to a cell
3. try to undo and fail

fwiw, i have "files.autoSave": "afterDelay" with "files.autoSaveDelay": 500
