This is a spin-off of bug 1297300, which is adding checking for GetSpec() calls that are lacking them.

nsINode::GetBaseURI() has a GetSpec() call that is fallible. The right way to handle this is to make nsIDocument::GetDocumentURI() itself fallible. bz noted in bug 1297300 comment 31.

It should also be marked with MOZ_MUST_USE, of course :)
Please let me know if this should be a higher priority than "backlog".

That seems fine. Thank you for checking.

Looks ok, but I'll defer to a DOM peer for r+.

Please add MOZ_MUST_USE here.

Also in this bug, I don't understand why to use ErrorResult, when nsresult is the normal way to propagate errors in Gecko, and ErrorResult is more like webidl layer thing.
