There are a few known issues already, but we are looking for any feedback on the look and feel of this feature before introducing it more broadly.

known issues:
Scrollable notebook output does not reveal find results correctly
notebook Error output is not scrollable
maximum limit message should not be within the scrollable region
scrollable output region keeps resetting scroll position

1. set "notebook.experimental.outputScrolling": true
2. Create a new notebook file
3. Run a few cells with large outputs
4. Play around with different combinations of related settings (might require reloading vs code): notebook.output.textLineLimit, notebook.output.wordWrap, notebook.outputLineHeight

Try on insiders.vscode.dev as well by either:
re-opening that same noteboook with output
or
Start up a jupyter server from a command prompt to provide kernels
1. python -m pip install jupyter
2. python -m jupyter notebook --no-browser --NotebookApp.allow_origin=*
3. copy the URL that the previous command provides and
4. open a notebook -> select kernel -> existing Jupyter Server -> paste the URL from step 3

great that this is being implemented! One feature I'm missing from jupyterlab is being able to toggle scrolling no/off for a specific cell using a keyboard shortcut

Specifically, for jupyterlab I have the following in the keyboard shortcuts json:

        {
            "args": {},
            "command": "notebook:enable-output-scrolling",
            "keys": [
                "S"
            ],
            "selector": ".jp-Notebook:focus"
        },
        {
            "args": {},
            "command": "notebook:disable-output-scrolling",
            "keys": [
                "Alt S"
            ],
            "selector": ".jp-Notebook:focus"
        },

Nice job. Feels like we are moving in the right direction. I would be happy to try it out again once we address some of the bugs :) Thanks
