\transn breaks vertical spacing inside of a square root

[barillax]

As shown below, when you put a decimal number into a square root, wrapped in \transn, it displays incorrectly. E.g.: \sqrt{\transn{0.04}}

I wonder if the fix for this might be similar to https://github.com/OmarIthawi/arabic-mathjax/pull/16 ?

EDIT: this also happens for \transt{}{} inside of a square root, i.e.: %% \sqrt{{\transt{speed}{السرعة}}} %%

After looking at #16, I inspected the DOM and found that if I added the .mar class to the surrounding element, it fixed the display. See image below illustrating what I mean:

The top square root in the above image renders incorrectly, while the bottom one displays properly thanks to the CSS giving the span border-width: 0.45 em 0;

I'm not super familiar with the code, but it kind of looks like the issue here is that when you use one of the \trans* functions, the resulting token(s) don't have arabicFontLang set to ar, which leads to the code in https://github.com/OmarIthawi/arabic-mathjax/blob/master/src/html.js#L51 not being run to add the mar class?
