@dan still one step missing, after the unrolling with labels has processed, click on any of the dots. from then on at least i get this seen in the image below when i try to undo and i can undo forever nothing visible changes other than the list which gets longer and longer and longer and… hey longer 
. if i cmd z right after unrolling it still undoes as you described here.
i recently had reset my preferences which helped to resolve the Bug in DupBorder on PictureFrame but this issue remains. also seen in the new wip just recently released.
