I updated to iOS 11, and after doing so, the display font for MathJax has changed across the entire interface of my phone. As evidence, here is a screenshot I found laying around with its updated copy:
Let's define three partitions $P,Q,R$ on $[a,c]$, $[a,b]$, $[b,c]$ respectively:
$$P=\{x_0,x_1,...,x_k,...,x_n\}$$ $$Q=\{x_0,x_1,...,x_k\}$$ $$R=\{x_k,...,x_n\}$$
where $x_0=a,x_k=b,x_n=c$
As the function $f$ is integrable on both $[a,b]$ and $[b,c]$, for any $\epsilon/2>0$ there is a $\delta>0$ such that
$$\left| S(Q,f)-\int_a^bf(x)dx\right|<\epsilon/2$$
I’m a very font-sensitive individual1, and this is one I thoroughly despise (except for the new Q, which I actually prefer over the old one, which always seemed deformed to me).
Is there any way at all that I can change this?

Edit: After reading through MathJax.org, I believe the “old” font was “SVG” while the “new” font is “HTML-CSS.”
