Comment(by novoselt):
Yes, I had this problem when I was dealing with charts corresponding to
non-full-dimensional cones. We need to keep the information about
directions corresponding to torus factor coordinates, standard basis
vectors are not always the best choice. Magma calls these directions
"virtual rays" but I am not fond of this name. In any case, I was going to
work on it but after having #11400 in place to have a uniform access to
representations of different types of rays.
