[Bug] Able to pause right before boss death cutscene

### Description
I was fighting Gohma in the Randomizer with Boss Intros off. Right upon dealing the finishing blow, I was able to pause the game, which caused an audio bug stopping music while the game paused and no sound played until Gohma landed during the cutscene. The final hit sound did not play either.

In the vanilla game this isn't possible. Upon dealing the final hit of damage against a boss, it immediately jumps to the cutscene and suspends all player input.

In the clip below you can see this in action. It visibly looks like Gohma was damaged before the pause.
