“As for the subject, I would suspect that the Hierarchy in Rome would consider this an internal Romanian issue.”
I agree, though perhaps they might wish that the incident never happened. I sincerely doubt Rome had anything to do with it and it is as likely as not that this Metropolitan, given his history, might simply have presented himself for communion and the presiding Latin hierarch gave it to him rather than make a stir.
Individual hierarchs sometimes do and say silly and troublesome things. Some years back a very holy and wise Greek metropolitan here in America announced after the successful close of a joint commission on the filioque that he had “ended the Great Schism and established communion with Rome”. Though those that heard the remark, Orthodox and Latins, were too polite to laugh, he did end up having to issue a retraction and an apology, so this guy in Romania isn’t all alone on this sort of otherwise meaningless stunt.
I may be wrong, but my understanding is that the Catholic Church will give the Holy Communion to any Orthodox when they ask for it. The instruction to the Orthodox is to obey their bishops, however, if they ask, they will be given Communion.
Where does it say there was a Latin Rite Bishop even present?
It refers to the Presiding Romanian Catholic Bishop who was celebrating the Byzantine Divine Liturgy, therefore I assumed he was a Byzantine Catholic, not a Latin Catholic.
It would be a different discussion were it a Latin Bishop practicing intercommunion...
I have checked the Catholic Bishop in question is Romanian

Interestingly enough he was also a representative at the joint Theological dialogue in Baltimore, MD
