Got a couple of edge cases here. Magic Ex Libris in the third book has the masquerade breaking down owing to a large battle, and if the villain didn't cause or particularly want it, she's not above exploiting the resulting chaos. Then the fourth book deals with a conspiracy to weaponize magic in the newly unmasqued world in a way that will turn people against it. Would this count?
The other is Twilight Watch when Konstam plans to use a forbidden spellbook to grant everyone magic, which would indeed break the masquerade but sounds like another trope.
