AHA! Now that is a problem.
IMO Idril and her son Earendil were in turn acknowledged rulers of the Noldorin Exiles, though neither considered it fitting to use the title of High King/Queen as their people had been reduced to a huddle of refugees at the mouths of the Sirion.
Earendil of course never came back from his final voyage, and his sons disappeared in the sack of the Havens leading the surviving Noldor to take Gil-Galad, the next in blood, as their leader.
By the time Elros and Elrond reappeared Gil-Galad was well established and accepted in his role as King of the Noldor. Elrond would have been much younger and probably ill prepared to take over the job. Thus Gil-Galad remained King but Elrond was acknowledged as his second in command and eventual heir. A reasonable compromise acceptable to all parties.
This is, of course, just my opinion.
