Unable to Scroll Up in Jupyter Notebook

[ruidazeng]

Description

When attempting to scroll up in a Jupyter notebook, the view automatically bounces back down to the current position. This prevents the user from reviewing earlier cells or content above the current view.

Reproduce

1. Open a Jupyter notebook.
2. Execute a few cells to create scrollable content.
3. Attempt to scroll up to view earlier content in the notebook.
4. Observe the behavior: the view bounces back to the current execution cell.

Expected behavior

It should let me scroll up.

This persists across different machines. Tried it on my Windows 10 and MacOS as well.

Every time I scroll up, it pulls up down to the starting position randomly.

Thank you for opening this issue @ruidazeng! Could you share the version of Jupyter Notebook that you are using? We were not able to reproduce this on the triage call, but if you could share a video of the steps to reproduce and the behaviour you are seeing that may be helpful!

This is quite likely jupyterlab/jupyterlab#15795

The exciting part is that you say you can reproduce this reliably. If you can share the notebook which allows that and exact repro instructions as mentioned by Rosio I may be able to fix it.

I am using Jupyter 7.2.2 notebook. It seems similar to jupyterlab/jupyterlab#15795 indeed, I am unable to scroll away from active cells randomly. Sometimes I can, sometimes I can't, but this issue persists across my two laptops.
