LibWeb: Don't crash when evaluating XPath against a rootless document Problem: Crash when evaluating an XPath expression against a document that has no root element. Cause: mirror_node()’s DOCUMENT_NODE branch unconditionally mirrored document.document_element(). But a document may lack a root element — in which case, document_element() returns null. Fix: Return null from mirror_node() when the document has no root element. (The caller already maps a null mirror result to a failed evaluation, and raises an error in that case.)
