Add option to disable automatic scrolling to next cell.

[nasosev]

There is already an option "Always Scroll On New Cell** whose behavior is described:

Automatically scroll the interactive window to show the output of the last statement executed. If false, the interactive window will only automatically scroll if the bottom of the prior cell is visible.

But it should be possible to completely disable automatic scrolling (as is the default behaviour of Jupyter Lab). It is annoying when debugging as any error messages are automatically scrolled passed.

Lang: F#

Thanks

Thanks for the request @nasosev. We'll discuss it in an upcoming meeting.

Really looking out for this one too --- the scrolling doesn't seem to ever hit the right target for me as is.

I really need this

This can now be disabled via interactiveWindow.alwaysScrollOnNewCell

that setting seems to not be working for me currently, created a separate issue: https://github.com/microsoft/vscode-jupyter/issues/11127
