Re: [csswg-drafts] improve styling of <details>/<summary> elements (#9879)

I don't quite understand why there are only a [limited number of CSS properties](https://drafts.csswg.org/css-lists-3/#marker-properties) that can be used in `::marker`, which severely restricts details from being a truly customizable styled component. 

A very common use case is when arrows need to be animated using the `rotate` property.
