For <math>A \xrightarrow{b} C</math> the horizontal spacing is too tight.
Expected: The spacing should match that of <math>A \to C</math>.
You can compare with https://www.mathjax.org/#demo. Enter $A \xrightarrow{b} C\\A \to C$ to see the expected rendering.

This is a texvc issue.
The input A \xrightarrow{b} C is converted into A{\xrightarrow {b}}C for which the tight spacing is the expected behavior.

This was simple to fix
https://github.com/wikimedia/texvcjs/pull/38/files?diff=split&w=1
thereafter
A \xrightarrow{b} C becomes A\xrightarrow {b} C

https://github.com/wikimedia/texvcjs/pull/38/files?diff=split&w=1 here two lines were moved, tests adjusted and cleanup T246011. However, to understand how LaTeX computes the spacing requires more studing maybe cf. e.g., http://mirror.physik-pool.tu-berlin.de/pub/CTAN/info/lshort/english/lshort.pdf section 3.7 for a start.
