Description

Recently, in the standalone Jupyter notebook mode, I started to occasionally observe a scroll glitch.

Reproduce

It is unfortunately unclear what exactly is required to trigger this issue initially.

1. My notebook is relatively long.
2. The cell re-writes some text (using display.clear_output(wait=True), which ultimately fails with an exception.
3. After the cell stopped executing, start to scroll upwards, from the cell output towards the cell content
4. At some point roughly when the top of the just executed cell becomes visible, the view suddenly jumps to align the top of the next cell with window
5. You can do this several times
6. If you bring another browser window into foreground and then go back, the glitch is sometimes gone.

Expected behavior

Normal scroll.

Context

• Operating System and version: macOS 14.4
• Browser and version: Chrome 122.0.6261.112
• JupyterLab version: 7.1.1
• Windowing mode: defer

Related issues:

• Switch off the new overreactive interface jump to end of output behaviour? #14878 -> suggests windowing mode full -> layout is completely broken in this mode for me (cells expand out of the right of the window due to long lines)
• Erratic scroll jumps when performing actions in notebook #15693 -> appears to be connected with notebook "actions". no "action" is triggering the glitch here, just scrolling on it's own.
