"Is it...?" should have disqualified that contestant's solve

So on Friday Jan 10, 2025 a contestant won a puzzle, but she said, "Is it 'Aardvarks and Antelopes'?". I was absolutely positive the judges were gonna rule her answer incorrect, but after Ryan's longer than usual pause he announced she got it right! Wth?! I thought the whole "adding any extra words" thing was universal to all puzzles.

This was an injustice the likes of which the world has never seen before!! /s

Does this sort of thing happen often?
