Undo for ec.apply_transformation_coordinate

[usai-sylvain]

I am calling ec.apply_transformation_coordinate and right after ec.add_elements_to_undo(element_ids, 2) but that doesn't do the undo trick. I would call it with move_element_with_undo but that needs a vector...

any clues ?
Thanks

all good, add_elements_to_undo belongs before the transformation
