@Tyriar Im not familiar with the DOM renderer code - just to make sure there is not bigger problem behind the scenes - Is the element supposed to be missing under some circumstances? If yes - LGTM.

@jerch I couldn't repro the problem unfortunately, this is just a sanity check to prevent the exception which does happen (which we will need when strict null checks are enabled anyway). If there is a bug, someone might report it someday by saying a link doesn't work and give us a repro case.
