/**
 * One math expression from an answer, typeset with MathJax.
 *
 * biel-message swaps each `$$...$$` / `\(...\)` span in the Markdown for one of
 * these before parsing, the same way fenced code becomes a code-snippet. Being
 * a custom element is what makes it survive streaming: the reconciler in
 * biel-message never recurses into an element whose tag has a dash, so it syncs
 * the `tex` attribute and leaves the rendered math alone instead of rebuilding
 * it on every flush.
 *
 * The raw TeX shows through until MathJax has loaded and converted it, so a
 * blocked CDN degrades to readable source rather than an empty gap.
