The ::marker pseudo-element supports a limited set of properties: https://drafts.csswg.org/css-pseudo-4/#marker-pseudo
In Firefox this is controlled by the layout.css.marker.restricted pref, make sure it's set to true (the default).
Then, run the attached testcase:
<ul>
<li>list item</li>
</ul>
<script>
document.querySelector('li').animate([
{opacity: 0},
{opacity: 1},
], {
pseudoElement: '::marker',
duration: 1000,
});
</script>
Expected: opacity doesn't apply to ::marker so there should be no animation.
Actual: the opacity is animated.

Hopefully some tests give unexpected results here--otherwise this will need tests too
