White Space Remover - not Ok. :)
Try Minimize any container and then Maximize it when White Space Remover is On. Minimized, but not maximized.
Standart container and your container too...
I found that the hidden tag used for the DNN variables needs special characters. So, I added a rule to leave this tag without modifications.
So, I think it is fixed, and I will release it within a few days.
