While
https://wpt.fyi/css/css-pseudo/marker-font-variant-numeric-normal.html
uses nested ::marker, it's not the main point of the test.
In fact I was thinking of editing that test to allow it to pass on
implementations that do not support nested ::marker, but never got to
do it.
So I think you should add tests specifically for this.
Also, I don't recall whether the flag allowed nested pseudo-elements
in getComputedStyle, but I tend to think it should.
See https://github.com/w3c/csswg-drafts/issues/4456, it may need a
quick CSSWG resolution to align with what was resolved for web animations.

and ::after::marker pseudo elements and will be essential to style
::column::scroll-marker pseudo elements for the carousel project
(https://github.com/flackr/carousel/tree/main/fragmentation
<https://github.com/flackr/carousel/tree/main/fragmentation>).
Specification

pseudo elements. So far, support is defined for: ::before::marker
::after::marker With ::column::scroll-marker being supported in
the future.
