Tagging @RRosio as suggested by jweill-aws.

Closing / Reopening to retrigger CI.

Looks like only 3 CI jobs have run. Is this expected?

[echarles]

@dylanramzn I think the CI was previously run on Travis which has probably been desactived. Do you think that you could backport the GitHub actions used in the 6.5.x branch ? https://github.com/jupyter/notebook/tree/6.5.x/.github/workflows

[echarles]

We have discussed this at the last community call with @jweill-aws. There has been a consensus to merge an release without a running CI, assuming the minimal sanity checks are done on a local env. This exceptional procedure is applied based on the nature of the change (jQuery front-end dependency upgrade being used all over the world).

I have tested locally this branch and as a user it works fine. I have also run the pytest command which returns 4 failed, 244 passed, 1 skipped, 1 xfailed, 71 warnings, 7 errors in 32.19s and was not able to successfully run any javascript test. The js failures are repicable on the vanilla 5.7.x branch. We could invest more time to make the javascript test work again but I wonder if this is worth to do that as we also said during the meeting that this will be the last patch accepted on this 5.7.x. branch.

@dylanramzn BTW the latest jquery version is 3.6.0 and you are using here 3.5.0. Any reason for that?

@dylanramzn Another thing to add is that pinning the dependency, jinja2 to a version <= 3.0.0 is necessary, as the more recent versions of jinja2 package cause import errors. I've verified this with a clean environment and a source package install which currently installs the most recent jinja2 version 3.1.2

Current Output with Jinja2==3.1.2

This PR was originally just a back port of the commit made previously for Notebook 6. #5491

@RRosio I changed it to jQuery 3.6.0, and pinned jinja2 to <=3.0.0. I ran a sanity test and verified I can open a notebook and execute 1+1.

This PR looks good so I will go ahead and merge!
