This:
\documentclass{minimal}
\begin{document}
$\left( 1 \right)$
$\left( \underbrace{1}_{456} \right)$
\end{document}
produces:
which is very ugly. There are several different things one could imagine would happen:
- The underbrace is totally ignored for sizing the parentheses (but of course it counts for spacing to the next line of text).
- The underbrace + actual line fill out the parentheses all the way, i.e. their center drops below the center of the no-underbrace parentheses and the line.
- The parentheses take the underbrace into account just partially.
I'm assuming the first would be simplest, so - how do I make that happen? Using phantoming perhaps?
Also, if you have another alternative/idiom for how to handle this situation 0 that would be appreciated.
Note: This question is about the simple case where the entire contents of the parentheses is covered by a single underbrace.

with measuring the length and applying it late in the extra vertical space.
