Italians (Venetians) came to Kvarner and Dalmatia after Croats had lived there for centuries. Italians only lived along the west Istrian coast before the Slavic majority but we took that as compensation for the early 20 century Italian expansion.
Furthermore the native balkan formerly Dalmatian-Romance speaking population is mostly still living in Dalmatia, they just speak a Slavic language now.
