[csswg-drafts] [css-lists-3] Should unicode-bidi / direction apply to ::marker? (#3809)

fantasai has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-lists-3] Should unicode-bidi / direction apply to ::marker? ==
CSS Lists 3 currently lists `::marker { unicode-bidi: isolate; }` in its UA default rules. This is good, markers should be bidi isolated. However, unicode-bidi isn't listed in css-pseudo-4 as a valid property on ::marker. Options:

- Make `unicode-bidi` and `direction` apply to `::marker` and keep the UA rule.
- Just make marker's automagically bidi-isolated always.
