mhchem arrow length in chromium

[ermv]

Hello!
mhchem arrow length is too short in Chrome when using STIX. Works fine in Firefox though. It can be reproduced on temml official website with this TeX: \ce{A->B}
Is there any workaround?

Is there any workaround?

None that I am aware of, and I've looked pretty hard. Two years ago, I opened an issue in the Chromium bug tracker. There has been no action (that I am aware of) so far.

On my own pages, I ship the Latin Modern font, partly to get better rendering of this feature.

I found a hack: somehow backwards arrow stretches fine and I can use it and then mirror with css. Steps to reproduce:

1. TeX : \ce{A <- B}
2. CSS:

.mirror {
      -moz-transform: scale(-1, 1);
      -webkit-transform: scale(-1, 1);
      -o-transform: scale(-1, 1);
      -ms-transform: scale(-1, 1);
      transform: scale(-1, 1);
    }

3. Add class to tag with arrow
   <mo stretchy="true" lspace="0" rspace="0" class="mirror">←</mo>

Works ok in both Firefox and Chrome

That's creative!

My first impulse is to not put something like this into the library. It gives a screen reader false information and it would break documents someday in the future when I can use the proper character.

It is food for thought, though. Maybe I can find another workaround if I just work at it some more.
