Line breaks in mfrac, mroot, and msqrt

Created by: jmitsdarfer

Issue Summary

Is there any way for us to configure MathJax so that it cannot break in the numerator or denominator of an mfrac (this one would be highest priority because we feel this could affect the understanding of the equation the most) or inside of the radicand of an mroot or msqrt (still may be interested in this as well, though it'd be lower priority)? If the MathJax must break in order to fit, could it throw out some error where we could then be alerted to adjust the tagging or perhaps replace the MathJax output with a graphical equation instead? OR even better, could it just always force the scroll bar in these cases (similar to eq 7 in the attachment) rather than break the equation in the numerator or denominator of an mfrac or the radicand of an mroot or msqrt?

In some cases, we feel the meaning of the equation could be confusing to some people. In other cases, the meaning is probably still apparent but still there is a large extra space on the left. Please see attached for examples. Thank you! Large fractions and roots.docx
