When RecyclerView prefetches future ViewHolder via GapWorker, sometimes it does not invoke bind method on them (because prefetch result is omitted). When such ViewHolder is recycled, ViewCompat.setAccessibilityDelegate is invoked passing null as a parameter, leading to losing the original accessibility delegate, that was set on ViewHolder view during costruction.

When bind method is invoked, RecyclerView retrieves the original accessibility delegate, wraps it with its own and set the new delegate to ViewHolder. When such ViewHolder is recycled, RecyclerView retrieves stored original delegate and set it back to ViewHolder view. This logic is broken in some cases of GapWorker.
