Upon launching jupyter-lab.exe (version 4.1.8), a warning message (screenshot below) appears in dev tools. When I open a notebook file (content below) containing one markdown cell and one code cell, an error message is displayed. The problem seems to be associated with the markdown cell; removing the markdown cell allows the notebook to open without the error message. This occurs in both Edge and Chrome browsers. Despite these warning and error messages, JupyterLab functions properly.

@hailiang-shen Thanks for opening this! It looks like the warning is CSS-related. I'm not sure what the error represents, but another dev can look into this. I appreciate your report.
