That's not unexpected behaviour. Note the denominator isn't affecting the
layout here so your observation is equivalent to

\documentclass[11pt]{article}

\begin{document}

$\left(\frac{1}{}\right)$ and $\left(\frac{a}{}\right)$ are rendered
with brackets of different size, while the brackets of
$\left(\frac{1}{}\right)$ and $\left(\frac{2}{}\right)$ are rendered
with brackets of the same size.
\end{document}

which follows from the fact that 1 and 2 have the same height but 1 has
more height than a

But this due to the font metrics and TeX's rules for using them, not
anything to do with any texlive specific coding: you would see the same in
any tex implementation.
