As discussed on sagedevel, we need to make the Sage kernel be more explicit about when the output's mimetype is text/latex (instead of using text/html, which is generally unnecessaryI don't think we need to wrap the output in an HTML fragment or <script type="text/math">
. I could be wrong, but I think that might be a vestige from older versions of IPython notebook...

A solution could be to use Jupyter's native rich output for LaTeX, not the Sage's mechanism through the IPython extension %display. For this, it suffices to implement the method _repr_latex_
to all Sage objects, i.e. add the following to SageObject
:
def _repr_latex_(self): from sage.misc.latex import latex return '$' + str(latex(self)) + '$'
See e.g. this presentation of Jupyter display logic. This solves the pdf issue reported here.

Thank you very much for the fix! I've tested it on a few notebooks and everything works perfectly.

The fix introduced here broke ipywidgets in Jupyter notebooks, see #31513.
