If we've skewed our matching before hitting a null placeholder (e.g. we've inserted or removed an unmatched node) then let's pick up matching null placeholders from the skewedIndex.

Note I don't think we need to adjust the skew when we find a null placeholder, we treat it as "matching" the current node.
