The previous blocks (added in the middle) disappear after scrolling down

[yilanzheng]

Description

If I insert a code block in the middle, for example, add a code block below an existing block, and if I scroll down or execute this block, it will disappear. If I scroll up, it reappears again. However, after I execute the block, even if I scroll up, I can only go to the output, no way to ever see the code block again or to modify the code.

Expected behavior

Thank you for your contribution @yilanzheng! This issue has been reported previously in jupyterlab/jupyterlab#16373. Currently the workaround is to switch windowing mode from full to none or defer. Another option is to upgrade your browser to Safari Technical Preview.
