[css-lists] Examples use properties not allowed in ::marker

[Loirooriol]

According to CSS Lists,

Only a limited set of properties can be used on the ::marker pseudo-element. This list is defined in CSS Pseudo-Elements 4 §4.2 List Markers: the ::marker pseudo-element.

CSS Pseudo says that only font properties, color and text-combine-upright apply to ::marker.

However, in CSS Lists, various of examples use properties like content, text-align, width, display, unicode-bidi, position.

[SelenIT]

The CSS Pseudo spec has the following note:

It is expected that future specifications will extend this list of properties; however at the moment marker box layout is not fully defined, so only these properties are allowed.

Since the CSS Lists spec seems significantly less mature than CSS Pseudo spec, maybe it's expected that at the time CSS Lists spec is released all the open issues with marker box layout definition will be resolved and this limitation becomes outdated?

[gsnedders]

@SelenIT I believe that is the case. (i.e., you should consider List a future specification wrt Pseudo)

[Loirooriol]

If some properties can't be added to CSS Pseudo until CSS Lists is more mature, then I think these extra properties should be listed in CSS Lists meanwhile.

OK, I've fixed most of these except what's in the default UA rules. We'll need to figure those out a bit more, so filed #3809

[fantasai]

(We dropped the section on marker positioning, so cutting down css-lists-3 to match what's in css-pseudo-4 and css2.1, more or less.)

And fixed by adding #3809 and aligning with the list in css-pseudo-4.
