Exile windows created with exileIds will remain on the battlefield after a rollback. Ex: Jeska's Will or Oblivion Ring

Steps:
1. I cast [[Jeska's Will]] which was exiled through the cascade ability on [[Bituminous Blast]].
2. I get an exile window with 3 cards in it. I play one of the cards.
3. I roll back

The exile window remains there, and the cards still say they're playable (they can't be played if you try).
