This is caused by a bug that I noticed by code inspection while working on bug 668941 and was going to file as soon as I had worked out a reftest for it. It's a regression from 665837: when we break off traversing frames because the last sibling is before the newline, we shouldn't be calling ResolveParagraph.

This fixes a regression from bug 665837 which was checked in on Aurora, so the fix should go on Aurora too. Beta is unaffected.
