Race condition when DI instance is not initialized. UninitializedPropertyAccessException lateinit property xxxxxx has not been initialized #1301

This is a race condition in EpoxyViewHolder that, when the child view contains Dagger DI. Potentially, it complains UninitializedPropertyAccessException lateinit property xxxxxx has not been initialized. It's 0.7% chance to run into this exception.
