memo1594 has a fake undertilde using ulem's uwave which made me look a bit deeper.
We currently have
|
\DeclareMathPassThrough{accentset}[2] |
|
|
|
\newcommand{\undertilde}[1]{\TeXMLCreateSVG{$\undertilde{#1}$}} |
I'm not sure why undertilde was implemented via \TeXMLCreateSVG but mathjax-ams-macros already supports \accentset and \underaccent is easy to match. (The other macros seem to be shorthands so they'd also be easy.)
