LATEX: \setparstyle needs some tweaks

[oscarlevin]

@davidfarmer shared an example of a sidebyside that was overflowing in LaTeX due to a \setparstyle in the sbspanelstyle. This might also relate to an issue with paragraphs indents in proofs.

In any event, we should sure this up. Need to be careful about paragraphs inside a sidebyside though.

I can take a stab at this, unless @Alex-Jordan has a quick fix.

Is there a place I can see the example of this?

OK, I figured out this is part of @davidfarmer 's recent post about a journal article.

I believe the issue here is not about \setparstyle. Rather it is that for an image (or a tabular) in a sidebyside, there should be no indentation. I am about to open a PR that does that.
