Sorry, my suggestion was not quite correct. The goal is to make sure that all the language describing how scrollMargin is applied is reachable from the algorithm description for "Compute the Intersection of a Target Element and the Root". That algorithm description currently refers to the [[scrollMargin]] slot, as distinct from the scrollMargin argument to the IntersectionObserver constructor.
I think instead it would make sense to put these two paragraphs back where they were, but add a line like 'To <dfn>apply scroll margin to a scrollport</dfn>' above it. You should also move lines 291-292 ("<b>These offsets are only applied...") to the same place; and then refer to this new definition in the algorithm description for "Compute the Intersection of a Target Element and the Root", instead of referring directly to the [[scrollMargin]] slot.
Hopefully this makes sense...
So I think these two paragraphs should be moved to the place where the [[scrollMargin]] slot is defined; and the text on lines 291-292 ("These offsets are only applied when handling...") should also be moved there.

Let me know if this looks better.
