Summary:
"The instance should not stick around after unmount..." - Tim Yung, 2021
I have a hypothesis that, if a component instance of an animated component sticks around after unmount, it could cause memory leaks due to references to Fabric ShadowNodes across the JSI (this would not impact non-Fabric... in theory).
Wild guess. If OOMs disappear then maybe this hypothesis is correct, but it's a long shot. I figure there's ~no harm in doing this cleanup here anyway.
