Additional information
It seems to be related to how long the term is. For instance,
$$
\underbrace{\frac{a}{b}}
$$
$$
\underbrace{\frac{a}{b}\frac{a}{b}\frac{a}{b}}
$$
and
$$
\underbrace{\frac{a}{b}\frac{a}{b}\frac{a}{b}\frac{a}{b}\frac{a}{b}\frac{a}{b}\frac{a}{b}}
$$
This should be an easy fix because I think LaTeX usually adds dashes to make the braces match the size of the term.
