If you can, this points to a problem that is outside of JupyterLab, such as a problem with the kernel, the notebook server, etc. Try to reproduce the issue in the classic notebook (make sure to launch it from the JupyterLab help menu).We've had issues before where a browser extension was changing the page under JupyterLab, creating very unpredictable problems. Try to reproduce the issue after turning off chrome or firefox browser extensions, particularly browser extensions that modify webpages.This checks to see if the issue has been fixed in the current JupyterLab, or if the issue comes from an extension, not JupyterLab itself. If you are using conda, create a new environment with conda create -n jlab-test -c conda-forge jupyterlab and activate the environment with conda activate jlab-test, then start jupyter lab. In a new environment with just the latest JupyterLab installed.If you are having this issue, please see if you can reproduce it:



If you are saying that this is also a problem with classic notebook, that indicates this is not a problem with JupyterLab. Also using the regular notebook interface
