Example CI is failing on master and PRs

[jtpio]

Description

Similar to #13481

But opening a new issue since the failure is different now:

Reproduce

Happening on the latest commit on master: 0adbcfe

https://github.com/jupyterlab/jupyterlab/actions/runs/3685583836/jobs/6236731860

And any other PR, for example: https://github.com/jupyterlab/jupyterlab/actions/runs/3684478101/jobs/6234263009

Expected behavior

The check should pass.

Context

#13481

[fcollonval]

The error inducing the test failure is not the one resulting in the above mentioned traceback.

It is the browser console error:

error >> Exception opening new comm

The traceback is induced by the kernel being stop with KeyboardInterrupt (so it is expected - in the sense that it can happen when the interruption happens very quickly).

[jtpio]

Closing since the examples check now seems to be passing on the latest master and new PRs.

Likely fixed by ipython/ipykernel#1056.
