Insert mode extremely laggy in Notebooks

Describe the bug

When editing or adding text in a Jupyter notebook there's a 1-1.5s delay between a typing a character and it being rendered to the screen. It makes it pretty painful to work on jupyter notebooks inside of vscode with the vim extension

To Reproduce

Open a jupyter notebook in VSCode with the VIM extension enabled. Edit a cell and go into insert mode and type any characters.

Expected behavior

Normal and visual modes work great with no perceptible lag. Turning off the VIM extension also removes lag when editing notebook cells

Additional context
Not sure if there are some settings similar to the previous vim.foldfix that might help with some additional processing the extension is doing specifically while inside a notebook
