The index of the top layer in the view starts with zero, while the rank of the layers count backwards. Thus moving the second-last to the last position should set the dirty flag of rank 0 and 1. Instead the former implementation set the dirty flag for layers >= 5, when moving "Red" to the bottom in the test map - resulting in the wrong layers saved.
