No focus when entering a Jupyter Notebook tab

See original GitHub issue

Bug: Notebook Editor, Interactive Window, Editor cells

Steps to cause the bug to occur

Open a tab with a .ipynb file with some cells (Python extension must be installed)
move a bit around: pressing j you select the next cell
now move the focus away from the tab and put it back in to the notebook tab, for instance press twice CMD+` in macOS to show and hide the terminal.
now you would expect to be able to interact with the notebook with the keyboard, for instance pressing k you would expect to select the cell above, but nothing happens
to restore the focus you have to click with the mouse in one cell

Actual behavior

Once going away from a .ipynb tab and going back in the focus is lost and you have to use click with the mouse to restore the focus

Expected behavior

Focus should be on the notebook, as what it happens with any source code tab.

Same issue here. I should emphasize that any action that moves focus away from the tab causes this issue.

Jupyter server running: Local
Extension version: 2020.5.80290
VS Code version: 1.45.1
jediEnabled: true
Python version: Python 3.8.2
OS: Ubuntu 20.04
Virtual environment: virtualenv

Further observations: if you are in a markdown cell, Alt+Tab away from vscode makes the notebook to go into command mode, and need to click the cell to make it editable. This does not happen when in a code cell.

Thanks for your feedback. This issue will be addressed once VS Code adds native support for editing notebooks. Please see https://github.com/microsoft/vscode/issues/91987. You can experiment by using VS Code insiders, which defaults to the new notebook experience.
