Disappearing minus sign (scaling problem with SVG fonts).
Created by: grahamandrewsmith
Issue Summary
We are using MathJax as part of a platform for setting exams for our calculus students. Recently, the minus sign has started disappearing on certain browsers at certain zoom levels. This would appear to be a problem with the SVG fonts.
Steps to Reproduce:
This can be seen, for example, on the following page at 50% zoom on Chrome.

Observe that the \leq sign is also incorrectly displayed at 80% zoom.
