Re: [csswg-drafts] [css-multicol-2] `column-height` and nested fragmentation (#11977)

And what if a spanner is fragmented in an outer fragmentation context, and the model is that a multicol fragment has row children, and a row has columns and / or spanners? How, then, can a spanner be split across multiple outer fragmentainers, if rows cannot be split?

Example:

```html
<!DOCTYPE html>
<div style="columns:3; column-fill:auto; line-height:20px; column-rule:solid; height:100px; background:yellow;">
  <div style="columns:2; column-fill:auto; column-rule:solid thin; background:cyan;">
    a<br>a<br>a<br>a<br>a<br>
    <div style="column-span:all; background:hotpink;">
      squirrel<br>
      squirrel<br>
      squirrel<br>
      squirrel<br>
    </div>
    b<br>b<br>b<br>b<br>b<br>
  </div>
</div>
```
