If a layman from the Eastern Rite is elected Pope, which Rite are they ordained under before becoming Pope?

When a layman is elected Pope, they are first ordained deacon, then priest, then consecrated bishop, then become Pope. For laymen in the Western Rite, it's safe to assume that their Deaconite is under the Western Rite, and same for their Priesthood and Bishophood. However, for a layman in an Eastern Rite, is their intermediary deaconite, priesthood, and bishophood under the Eastern Rite that they were respectively baptized in? Or are their intermediary positions under the Western Rite?
