The style border-spacing of parent element affects fractions rendering

[kwankyu]

This is observed with MathJax3 with CHTML rendering. For example,

      <table style="border-spacing:20px">
          <tr><td><span>$\frac{1}{2}$</span></td></tr>
      </table>   

display the fraction with too much spacing. SVG rendering is okay.

MathJax uses display:table to lay out the fraction, and so the border-spacing from your table is affecting that. A work-around for now is to set

mix-math {
  border-collapse: collapse
}

in your page's CSS. MathJax resets a number of CSS properties to avoid bleed-through from the rest of the page, but that is not one that gets reset. I will have to add it to the list of properties that are set for MathJax's output.
