Make mathjax work in abstracts of questions

I activated mathjax for questions and answers by adding the following lines to the Scripts HTML Section in the Admin Panel:

<script type="text/x-mathjax-config">
  MathJax.Hub.Config({
    tex2jax: {
      inlineMath: [ ['$','$'], ["\\(","\\)"] ],
      processEscapes: true
    }
  });
</script>


<script type="text/javascript" async
  src="https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.4/MathJax.js?config=TeX-MML-AM_CHTML">
</script>
<script>
talkyard.postElemPostProcessor = function(elem) {
  console.log('Telling MathJax to post process elem: ' + elem);
  MathJax.Hub.Queue(["Typeset", MathJax.Hub, elem]);
};
</script>

However this doesn't seem to work for the abstracts of the questions in the overview list. So how can I make it work there as well?
