PS, you really should update your version of MathJax. v2.7.1 is quite old. The current version is 3.2.2, with v4.0 out in beta release. The current v2 version is 2.7.9.

I know what is causing the problem, and it is fixed in the upcoming v4 release (currently in beta). Unfortunately, I have not been able to workout a patch for...

No problem. At least it gives me an issue to tie the branch for the PR to.

Actually, this was fixed in a recent [commit](https://github.com/mathjax/MathJax-src/pull/827/commits/597cbcab831da89f256fe2f0d0bccab115eef4f7) to the linebreaks branch, since that hasn't been fully reviewed and merged yet, so it didn't get a separate PR.
