For compatibility with Parsoid's document abstraction (Parsoid may switch to an alternate DOM library in the future), don't explicitly create a new document object using `new DOMDocument`; instead use the Parsoid wrapper `DOMCompat::newDocument()`. This ensures that the Document object created will be compatible with Parsoid. There are a number of other subtle dependencies on the PHP `dom` extension in DiscussionTools, like explicit `instanceof` tests; those will be tweaked in a follow-up patch (I3c4f41c3819770f85d68157c9f690d650b7266a3) since they do not affect correctness so long as Parsoid is aliasing Document to a subclass of the built-in DOMDocument. Similarly, the Phan warnings we suppress do not cause runtime errors (because of the fixes included in c5265341afd9efde6b54ba56dc009aab88eff83c) but phan will be happier once the follow-up patch lands and aligns all the DOM types.
