Hi @hyperkai. Thank you for creating this issue.

We were not able to reproduce the issue so far. We've tried reproducing it in the versions of JupyterLab and Notebook that you use as well as in the latest versions.

Could you please double check that this is not a font / rendering confusion issue where commented out 't' rendered in italics just looks similar to 'm'?
