The Working Group just discussed `column spanning issues`, and agreed to the following resolutions:

* `RESOLVED: Column span applies to elements lower than the first level of descendants as long as it's part of the same formatting context.`

<details><summary>The full IRC log of that discussion</summary>
&lt;eae> Topic: column spanning issues<br>
&lt;eae> github issue: https://github.com/w3c/csswg-drafts/issues/1072<br>
&lt;eae> rachelandrew: Three issues all referring back to each other. Main issue is 1072. Propose we resolve it first and then refer back to it.<br>
&lt;eae> rachelandrew: Quite a long issue. dbaron raised it and florian commented quite a lot.<br>
&lt;eae> rachelandrew: Quick summary: When you got an element with column spanning and they're not a direct child of the multicol box container and they're still spanning. The definition says what happens to the ancestor. A good example would be a section with headings and one of them has span all.<br>
&lt;eae> rachelandrew: Was discussed on a call in May, June, and then went back to discuss on github and then stopp.ed<br>
&lt;eae> rachelandrew: Perhaps we shouldn't allow these nested things to span.<br>
&lt;eae> fantasai: There was some comments on allowing nesting of block but not things within another formatting context. Seems like a reasonable compromise.<br>
&lt;eae> fantasai: I don't think it is particularly useful for it to pop out as long as regular block elements work. The restriction makes sense from a behavior and implementation point of view.<br>
&lt;eae> fantasai: It is what I'd expect to happen it it makes what implementations seem to do. Makes sense to specify that behavior.<br>
&lt;eae> rachelandrew: I'd be happy to draft that up, makes sense to me.<br>
&lt;eae> fantasai: Happy to review spec text.<br>

&lt;iank_> ?<br>
&lt;eae> fantasai: Arbitrary depths but you cannot cross a formatting context.<br>
&lt;eae> fantasai: Header inside a section is a good example.<br>
&lt;eae> Proposed resolution: Column span applies to elements lower than the first level of decendence as long as it doesn't cross a formatting context<br>
&lt;eae> RESOLVED: Column span applies to elements lower than the first level of descendants as long as it's part of the same formatting context.<br>
