From bug 1988225 comment 2: https://codepen.io/yisi/pen/yLrjKEO (The case is using ::-webkit-slider-thumb as well that we don't recognize)
Seems reasonable enough?

I added ::-moz-range-thumb to the original demo and forked a new one.

Please note that in the demo, there is also a new behavior for anchor-center. Refer to WebKit bug: https://bugs.webkit.org/show_bug.cgi?id=294575

I'm just creating a PR to add information about this issue to MDN. Once this bug is fixed, we'll need to remove it again.

Argh, this isn't as simple as putting the pseudo in the allowable anchor list - need a mechanism to update the positioned element on the range slider being updated.
