"U" (undo, command in Vim keybinding) does not work

[siva-msft]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.59.0-insider
• OS Version: Windows 10, Version 10.0.19043 Build 19043

Info:

All the other vim comands, such as "x" to delete a character or "DIW" to delete a word work, except for "u" for undo.
However, when I press Ctrl +Z - that works alright.

Attached video for reference.

This issue occurs only in Notebooks, the regular editor works fine. Should I keep this issue here, or file it in the vscode-jupyter repo?

@siva-msft thanks for reporting this issue. I'll take a look. We might need some change in the Vim extension.
