Long division problem text not formatted correctly

[bree-z]

I'm not sure if this is related to #143 , but the parts of the long division problem text isn't being formatted correctly on the OL-WW side. E.g.:

OL-WW: http://openlabdev.org/webwork-playground/#:problemId=local2/setPolynomial_Division/long-division-nonmonic-linear.pg

WW

OL-WW

Thanks!

Apologies if this should have been part of #131 !

There's a slight relation to #131, because the particular formatting of this problem means that empty LaTeX chunks are getting pushed to OL-WW. I've just added a check that ensures that these empty chunks are not processed by the browser.

The root issue here is that the formatting in the long division problem is not native LaTeX, but appears to be powered by the creative use of inline div styles. This styling was being stripped by my security tools. I have loosened the restrictions for this type of content and it appears to resolve the issue. This will only apply to newly posted items - existing ones are in OL-WW without the full markup. See eg http://openlabdev.org/webwork-playground/#:problemId=local2/setPolynomial_Division/long-division-nonmonic-linear.pg:questionId=11806

cc @drdrew42 just as a heads up about the display: table-row etc tricks. It's fine to use them but it's good to keep in mind that new things like this will likely need to be whitelisted in the future.

Thanks, Boone! I've tested a bunch of these, and all seem fine.
