[css-pseudo] Default UA styles for markers don't affect ::before::marker and ::after::marker · Issue #4474 · w3c/csswg-drafts (original) (raw)

From https://drafts.csswg.org/css-pseudo-4/#marker-pseudo,

UAs must add the following rule to their default style sheet:

::marker { unicode-bidi: isolate; font-variant-numeric: tabular-nums; }

But ::marker only selects markers originated by elements, not by other pseudo-elements.

So I guess the selector should be ::marker, ::before::marker, ::after::marker.
