[csswg-drafts] [css-lists][css-counter-styles] Define which symbols are not affected by font-family, and how exactly (#6201)

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

== [css-lists][css-counter-styles] Define which symbols are not affected by font-family, and how exactly ==
If you have this code:
```html
<!-- AdobeBlank defined in https://github.com/adobe-fonts/adobe-blank/blob/master/adobe-blank.css -->
<ol style="font-family: AdobeBlank">
  <li style="list-style-type: decimal">1.</li>
  <li style="list-style-type: circle">◦</li>
</ol>
```

Then the font displays both `1.` of the ::marker and text node as blank.
But in the 2nd item, we still see the `◦` of the ::marker, only the text node is blank.

This was kinda explained in CSS2 https://www.w3.org/TR/CSS22/generate.html#list-style

> Glyphs are specified with `disc`, `circle`, and `square`. Their exact rendering depends on the user agent

However, according to https://drafts.csswg.org/css-counter-styles-3/#simple-symbolic, `circle` is just supposed to produce a U+25E6 `◦`, and CSS Lists doesn't say that ::marker should change the font-family or something.

So reading the specs I would guess that the `◦` should disappear too, but that's probably bad for compat.

So I think the specs should define what exactly happens. Implementations haven't been much consistent in the details:

 - Is it just for `list-style-type` set to `disc`, `circle`, `square`, `disclosure-open`, `disclosure-close`? What if their definition is changed using `@counter-style`?
 - What if I use my own `@counter-style` like
   ```css
   @counter-style my-circle-1 { system: cyclic; symbols: "◦"; suffix: " "; }
   @counter-style my-circle-2 { system: extends circle; }
   ```
 - What if I use `list-style-type: "◦ "` or `::marker { content: "◦ " }`?
 - What if I use `::after { content: counter(c, circle) }`?
