Set cursor to be <symbol> element

I have an HTML symbol

<symbol id="arrow" viewBox="0 0 8.4666659 8.4666659">
  <g transform="translate(0,-288.53334)">
    <path style="fill:none;stroke:#000000;stroke-width:0.48417112;stroke-linecap:butt;stroke-linejoin:miter;stroke-miterlimit:4;stroke-dasharray:none;stroke-opacity:1;" d="m 0.17215798,288.70836 8.05225192,8.04935"></path>
    <path style="fill:none;stroke:#000000;stroke-width:0.48417112;stroke-linecap:butt;stroke-linejoin:miter;stroke-miterlimit:4;stroke-dasharray:none;stroke-opacity:1;" d="m 8.2221335,293.64243 0.00228,3.11528 -3.1283502,2.2e-4"></path>
  </g>
</symbol>

which I want to use as the cursor. I’m familiar with changing the cursor via JQuery like this:

body.css('cursor', `wait`);

But how can I do this for a <symbol> element?
