Summary: \overleftrightarrow incorrectly parsed

#overleftrightarrow
OS/Version: All
Status: NEW
Severity: normal
Priority: Normal
Component: texvc
AssignedTo: [email protected]
ReportedBy: [email protected]
The overleftrightarrow is an ams-math function. However, Texvc treats it like
it is a TeX function.
For example, <math>\overleftrightarrow{AB}</math> will throw the error " Failed
to parse (PNG conversion failed; check for correct installation of latex,
dvips, gs, and convert): \overleftrightarrow{A B}
Whereas, <math>\mathit{i}\overleftrightarrow{AB}</math> works.
I believe that the parser/tokenizer just needs to specify amsmath when it comes
across \overleftrightarrow in the code. My workaround right now is dumb, such
that I just force ams-math to be used in all latex processing.
