[csswg-drafts] Pull Request: [css2] Fix wording for magins collapsing

Psychpsyo has just submitted a new pull request for https://github.com/w3c/csswg-drafts:

== [css2] Fix wording for magins collapsing ==
This matches the notes below that section and also matches implementations.
Consider:
```html
<!DOCTYPE html>
Foo
<p><span style="display: block; margin-block: 1em"></span></p>
Bar
```
The current spec suggests that, since this paragraph has an in-flow child, its margins should not collapse, when in reality, all the margins here collapse into a single `1em` gap, because there's nothing in-between.
