Jupyter Notebook stoles keyboard commands when WebView is focused

[iurii-iufimov-forgood]

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

To reproduce the bug you need to have another extension that uses webview. For example:
https://github.com/microsoft/vscode-extension-samples/tree/main/webview-view-sample

Steps:

1. Start VSCode with Jupyter and WebView-based extensions enabled
2. Run "Create: New Jupyter Notebook" command
3. (Create and) focus new code cell
4. Focus text input inside WebView ("Explorer -> Calico Colors -> New color" in the provided example extension)
5. Run text edit command via keyboard (e.g "Ctrl/Cmd+X" to cut)
   Actual result:
   Code cell is removed.
   Same is actual for other text edit commands: Paste, Cut, Undo, Redo
   Expected result:
   Text edit commands inside webview don't affect opened Jupyter Notebook

Thank you for filing this issue and sorry you are running into this.
Do you experience similar issues with regular text editors open.
I.e. open a text file and try to replicate this same issue with the webview.
Asking as I'd like to determine whether this issue is scoped to just the Jupyter Notebooks or other editors as well

[iurii-iufimov-forgood]

@DonJayamanne , no, regular text editors don't produce the same error.

Oh, now I've got your question. No, actions in Webview don't affect regular text editors, only the Jupyter Notebook

[iurii-iufimov-forgood]

@DonJayamanne , is the tag "info-needed" is relevant anymore?

Hey @DonJayamanne here's a related issue - in the comments I've added steps to reproduce and more screen-recordings.

Answering questions that you had above - this is only experienced in notebooks.

• The cut command is hijacked (try cutting a string and you get a cell in the editor being cut)
• The paste is being hijacked only if a cell has previously been copied or cut from the notebook editor

Let me know if I can do anything to help identify the root cause or even fix
