Faces "leaking" out into output area.

[indigoviolet]

This is probably in the bucket of polymode weirdness, but I notice occasionally that font lock and faces are leaking out into the output area. When data is printed in the output area, this can result in font lock thinking there are "unclosed quotes", and everything looks weird from there on.

I'd be happy with some ad hoc fix that I can deploy when I see this happening; but I am unable to trigger "re-fontification" of all cells and the output areas. If I disable and re-enable font-lock mode in the notebook buffer, all colors disappear, including in the cells.

Any suggestions? For instance, can I toggle font-lock in every (python-mode) cell?

Thanks for your work on ein!
