Crash with RecyclerView

[Lebartodev]

I came across a crash when implementing RecyclerView + Rive.
It is easy to reproduce it if you remove the riveResource tag from activity_recycler_item.xml, run RecyclerActivity, scroll down 3-4 items and then return to the beginning.

I think this is because in onDetachedFromWindow you call RendererSkia.delete(), which clears the unsafeCppPointer for LinearAnimationInstance ( by RendererSkia.disposeDependencies()). And in onAttachedToWindow, play(detachedState.playingAnimationsNames,...) is called with names of LinearAnimationInstance that no longer exist in C++.

Caused by: app.rive.runtime.kotlin.core.errors.RiveException: C++ object for app.rive.runtime.kotlin.core.LinearAnimationInstance@6c6335 does not exist. See MEMORY_MANAGEMENT.md for more information.
