This PR fixes a problem with the
multline
environment where it was incorrectly getting a frame. That was due to changes with how theframe
attribute was being handled, and the fact that I had used an emptyframe
attribute to add theframespacing
without a frame. That was a misuse of theframe
attribute, which I knew would come back to bite me, and now it did.The fix is to change
multline
to usedata-array-padding
instead offramespacing
for the spacing. This also requires a fix in the CHTML output to properly handle that change as well.Resolves issue mathjax/MathJax#3083.
