Node::compareDocumentPosition() reports an attribute and its content as disconnected.
Instead, the attribute should contain and precede its content.

This is causing the following test case to fail:
LayoutTests/dom/xhtml/level3/core/nodecomparedocumentposition38.xhtml

I investigated the issue a bit and it seems the problem seems to be that Node::inDocument() returns false for the Text node (content) instead of true.

Note that there is already a workaround in place in Node::compareDocumentPositionInternal() that addresses the same issue for Attribute nodes.

See comment in that method:
// Note that we avoid comparing Attr nodes here, since they return false from inDocument() all the time (which seems like a bug).

It is likely we need to extend the workaround to Text nodes or fix the underlying problem (have inDocument() return correct values for Attr and Text nodes).
