It seems there are somes bugs with nested fragment that have an interaction operand : interaction operand of child fragment is sometimes automatically re-associated with its parent fragment.
Also interaction operand of alt fragment is automatically resized to the alt fragment size when the fragment is resized (but you usually want it to split the alt fragment into two)
Finally ref fragment name is not displayed until you close your diagram and reopen it.
