[csswg-drafts] [css-selectors-4] ::text / ::text-node pseudoelement

Nadya678 has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-selectors-4] ::text / ::text-node pseudoelement ==
https://drafts.csswg.org/selectors-4/

Please add `::text` or `::text-node` selector to select all text nodes inside any element
for example for 
```
<p>
   #text1: Here is text
   <span>
      #text2: Here also is text
   </span>
   #text3: Here is second text in the paragraph
</p>
```

the `p::text` will select #text1 and #text3 and the pseudoelement can be styled like` ::after` and `::before` (without need to set "content").
