        The list is reverted to use LinearLayoutManager only. The issue of random crashes lies in
        the way StaggeredGridLayoutManager invalidates view in LazySpanLookup. Since we're adding
        items in between full-span items the array is not yet invalidated and consecutively crashes
        due to index of -end- being out of bounds of the current array.

        If you'd like to use StaggeredGridLayoutManager, do so without adding single span items in
        between of full-span items.
