MathJax doesn't complete initialization in IE9 when in IE9 Standards mode
Created by: shogun70
- Using IE9 Platform Preview 5, visit http://mathjax.org/demos/tex-samples/
- The TeX equations remain unprocessed
- Use IE Developer tools to switch the page to IE9 mode - the equations are still unprocessed.
IE notifies of an error at around line 1815 in MathJax.js Specifically, there is a comparison (RegExp.$2 !== "") which seems always valid on other browsers, but not in IE9.
