Arrows <=>> and <<=> are not strechy

[david15566]

Hi all! I having some troubles with the mhchem arrows. If I write some code like: \ce{<=>[{some text}][{Some text}]} --> Mathjax bring me a little arrow not adjusted with the text.

With other arrows: \ce{<=>>[{some text}][{Some text}]} \ce{<<=>[{some text}][{Some text}]} Both of them bring me the same arrow like the example below (\ce{<=>}) instead of the correct arrow.

I write this using the documentation available at ftp://www.ctan.org/tex-archive/macros/latex/contrib/mhchem/mhchem.pdf

Hi david1566!

First of all, please refer to the MathJax/mhchem documentation and not the LaTeX/mhchem one.

The non-strechiness of <=>> and <<=> is a feature request towards MathJax. https://github.com/mathjax/MathJax/issues/1491
