The general setup is that the State struct is used to iterate over text nodes explicitly, and keeps references to the ranges so that we don't need to pass all them around everywhere. We need to teach nsFindContentIterator to rewind into NAC to be able to get rid of mIterNode, which was getting out of sync when we failed to rewind to the anchor node.
