Description

In a cell with several hundred lines, I expect Ctrl-o, z, z to center the line I have selected in the viewport; instead, it changes my line selection (o_O) and … doesn't seem to center anything.

Correspondingly, Ctrl-o, z, t changes my line selection, and then moves the viewport to the top of the cell.

Research direction
Reproduce the issue in a Jupyter notebook with a long cell. Investigate the implementation of `zz` and `zt` commands in the plugin's codebase, likely in a Vim script or JavaScript file. Check for any updates in Jupyter's API that may affect viewport positioning. Look at the repository's issues and PRs for previous attempts or discussions about this behavior.
