Does this issue occur when all extensions are disabled?: Yes/No
- VS Code Version: 1.58.0 Insiders
- OS Version: macOS Big Sur
Steps to Reproduce:
- Click on an output or an input box in the native interactive window
- Execute the "Jupyter: Clear Cells" command
Expected: Cells Cleared
Actual: Nothing happens
Checking the code it seems like window.activeNotebookEditor is only active if you click on the document tab or on the input box of the native interactive window. Clicking anywhere in the main area (input and output history) the document is inactive even if an editor cursor is in it. You can see as the title bar remains grey.
