Replacing a character with j or k in a jupyter notebook can move between cells

[apuranik1]

Describe the bug
When trying to replace a character in the first line of a jupyter cell with k, or a character in the last line with j, focus shifts to another cell.

To Reproduce

1. Make a jupyter notebook.
2. Make three cells and one line of text in the middle cell.
3. Put the cursor on any character in that line and type rj in normal mode. Your cursor ends up in the next cell.
4. Move back up to the previous cell with k, then press any character except j or k. The first character of the line gets replaced with that character.

Expected behavior
The character should have been replaced with j in step 3.

I now believe this is an issue with the Jupyter Keymap extension. I fixed the problem with the following new entries in keybindings.json:

	{
		"key": "j",
		"command": "-notebook.focusNextEditor",
		"when": "editorTextFocus && inputFocus && notebookEditorFocused && vim.mode == 'Normal' && notebookEditorCursorAtBoundary != 'none' && notebookEditorCursorAtBoundary != 'top'"
	},
	{
		"key": "k",
		"command": "-notebook.focusPreviousEditor",
		"when": "editorTextFocus && inputFocus && notebookEditorFocused && vim.mode == 'Normal' && notebookEditorCursorAtBoundary != 'bottom' && notebookEditorCursorAtBoundary != 'none'"
	},
