[krassowski]

Can you add a screenshot demonstrating the issue please?

[soerenwolfers]

@krassowski Sorry, had taken the screenshot but not pasted in. Edited the OP now to add it.

[krassowski]

Does it happen consistently? Does it also happen in 7.2.1?

[soerenwolfers]

Does happen across laptop restarts, complete browser refreshes, and in all notebooks.

Problem doesn't exist on Firefox+Notebook7.2.2.
Problem doesn't exist on Chrome+Notebook7.1.1. (and I can persistently obtain this fix by pip installing this notebook version; and I don't get the JS errors shown in the OP)
Problem does exist on Chrome+(Notebook7.2.1 or Notebook7.2.2). (and I can persistently reproduce the problem by pip installing these notebook versions)

[Mohammad-MZ]
