Copy/pasting from Jupyter Notebook leads to duplicated cells

[AlfredoSandovalx]

Applies To

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

What happened?

When I copy code or text from a Jupyter Notebook cell and try to paste it into another panel or extension, it causes duplicated cells to appear in the notebook.

See Sourcegraph cody bug #6200

Steps to Reproduce

1. Open a Jupyter Notebook in VS Code.
2. Copy the entire cell contents (code or markdown).
3. Attempt to paste the content into another panel or external application.
4. Notice that the notebook cells get duplicated.

Expected Behavior

Copying and pasting from the notebook into another panel/application should not affect the notebook cells. The text should simply paste without duplication.

Actual Behavior

Cells in the notebook get duplicated, and sometimes I need to click off the notebook tab to complete the paste action.
