Long math expression in output is not wrapped unlike notebook 6

[kwankyu]

Hi,

Testing notebook 7 with SageMath, we noticed long math expression rendered by MathJax 3 is not wrapped, unlike notebook 6.

See sagemath/sage#36129 (comment)

I hope this behavioral change is not intended. I think it is a bug.

• checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed
• I'm reporting the issue to the correct repository

I checked the issue on Chrome browser both with notebook 7.0.3 and jupyterlab 4.0.6

Just for context, this is a know issue in MathJax 3 and will probably be resolved by upgrading @jupyterlab/mathjax to MathJax 4 once it is released (see jupyterlab/jupyterlab#14570). For now you can install jupyterlab-mathjax2 to downgrade to previous MathJax version (which is a trade=off because that has performance impact).

I am not sure if this is the same issue with jupyterlab/jupyterlab#14570. The math expression does not use \\; it is a single long expression (a polynomial).

On the other hand, I could confirm that it is an issue of mathax3 vs mathjax2. No problem with Notebook 7 itself.

Thank you for attention.

Isn't it possible to fix this by an appropriate CSS styling of mjx-container?

I noticed that placing and evaluating an html cell in the notebook, like this:

%%html
<style>
mjx-container {
  overflow-x: auto;
  overflow-wrap: break-word;
  max-width: 50%;
  }
</style>

does make the window to show a displayed LaTeX formula narrow (50% width, as requested), but does not force formula wrapping.

It could be a bug/missing feature in MathJax-3, I don't know.

install jupyterlab-mathjax2 to downgrade to previous MathJax version (which is a trade=off because that has performance impact).

apart from performance impact, it breaks off-line display of MathJax. Not sure whether this can be considered a bug in jupyterlab-mathjax2.
