Fix: #2966

@DAVIDWALES if possible can you check if this fixes ur problem?

[ghost]

@pdet Is there a build artifact I can try? Or do I need to build from source?

[Mytherin]

Is there any way to add a test for this, e.g. could we run ipython in the CI somehow?

Task: #2966

Also minor note, github doesn't seem to recognize "Task:" as a closing keyword. If you could use "fixes" (or another term from that list) the PR will be automatically linked to the issue.

We add Ipython as a dependency, I'm not entirely sure how to capture the return value of the display function in order to assert that the query succeded

Could you look at the test failure? This seems related to the changes made in this PR.
