The pragma directives specification steps should only run when a meta element is inserted into the document, meaning it is in a document tree after the insertion steps have run. We previously ran the pragma algorithms for any insertion, so inserting a meta element with `http-equiv=content-language` into a detached subtree dereferenced a null document element.
