RE: [css-regions] margin of first paragrah of a region

Indeed, there are a lot of details to be flushed out.

Alan, could you please make a note for this for the next level of Regions/Fragmentation? I don't have editing permissions for the css-regions-4 page on CSSWG wiki.

Yes, it does. But how you actually define the first element is probably tricky. Out-of-flow elements may perturbate the whole thing, but maybe we could just rule them out of the count, but that makes this stuff a bit harder.

Anyway, the idea was to get the use-case logged, so that we could work on it when we'll have the opportunity to up the spec level.
