Re: [csswg-drafts] [css-pseudo-4] Allow to add a marker to each line (#13329)

`::line-marker` was found in the [2003 WD of the Generated and Replaced Content Module](https://www.w3.org/TR/2003/WD-css3-content-20030514/#line-markers). The _Changes_ section of the [2016 WD of the Generated Content Module](https://www.w3.org/TR/2016/WD-css-content-3-20160602/#changes) mentions that pseudo-elements had been moved to the [Pseudo-Elements Module](https://drafts.csswg.org/css-pseudo-4/), but this particular one did not resurface there. 

The [CSS Wiki](https://wiki.csswg.org/spec/selectors#ideas-to-consider) still mentions the idea to introduce an `::nth-line()` selector, but since this should obviously work like `::first-line`, it could never have a marker box and `::marker` pseudo-element itself, because 
1. any [sub-pseudo-element](https://drafts.csswg.org/selectors/#sub-pseudo-elements) needs to be allowed specifically – #4506 is about the inverse case, `::marker::first-line`, not `::first-line::marker` –and 
2. it is not fully stylable and [does not support](https://drafts.csswg.org/css-pseudo/#first-line-styling) the `display` property in general and its `list-item` value in particular, which is required to generate a marker box.
