Thank you for opening this issue @kuraga! This issue has been reported in the JupyterLab in: jupyterlab/jupyterlab#16928. This would likely be fixed in Notebook once a fix goes in for it in the JupyterLab codebased. I will label it as blocked to signal the need for work to be done in the JupyterLab code.
