Retain Sub-Object Selection After Moving or Transforming?

I’ve been working with sub-object selections (faces, edges, vertices) in Rhino, and I noticed that after I move or transform the selected sub-objects, the selection is lost.

Is there a way to retain the sub-object selection after performing transformations?

I did the same test since I also remembered it was something not happening before.
Indeed, when I start a new file everything is working fine, but I have some files where the feature is broken.
Can I share privately the file in question for you to have a look?
