Typing becomes slow and choppy in jupyter

[GBoGH]

Type: Performance Issue

When using jupyter notebooks, after a while, vscode becomes unresponsive/choppy when typing or removing text.

I didnt see this happen with any other file, just jupyter notebooks

We have made improvements to the typing issue in main branch. Can you please try VS Code Insiders and see if it helps? @GBoGH

[GBoGH]

I have not experienced any issues with the insiders version
