Notes

The spec requires that comparisons of nodes in different documents, and comparisons where at least one node is not in any document, must arbitrarily (but consistently) set either the DOCUMENT_POSITION_PRECEDING or DOCUMENT_POSITION_FOLLOWING bit in the result. These browser versions don't set either bit in some such cases.
Sets neither the DOCUMENT_POSITION_DISCONNECTED bit nor the DOCUMENT_POSITION_IMPLEMENTATION_SPECIFIC bit in some cases when comparing nodes in different documents or when comparing a node which is not in any document.
