[We strip these out when displaying error cells](https://gitlab.com/gitlab-org/gitlab/-/blob/master/gems/ipynbdiff/lib/ipynb_diff/output_transformer.rb#L33-33), we could apply the same logic to the output cells | Jupyter render | GitLab render | | ------ | ------ | |  |  | ## Implementation Guide 1. Within the ipynbdiff library, we have already have implementation to clean error outputs, we can do similar: https://gitlab.com/gitlab-org/gitlab/-/blob/master/gems/ipynbdiff/lib/ipynb_diff/output_transformer.rb#L33-33 2. Add a new test to https://gitlab.com/gitlab-org/gitlab/-/blob/2d84e7021eeb07e5da23a6e05017ee75da1777d0/gems/ipynbdiff/spec/ipynb_diff/transformer_spec.rb#L17
