That definitely sounds like some bug. I'll take a look at this.

Unfortunately that not how domains work, they are not proactive, one
has to manually updated them. One has to manually call
ResetToDefault() at an appropriate point after the information is
available. I'm certain the GUI does that, can't remember is the
behavior is exhibited by Python as well.
