You can't really blame the whole Jabina mess on HHA tbh. In HHA, Joy kissed Fabian 1 time as a dare, not becauss she liked him in a romantic way. Joy and Fabian never liked each other that way, not even before the time she disappeared, they were just good friends. And Nina in HHA, only got jealous for a little while, and it was all just in her head(thinking that Jabian liked each other etc), but even then she was never mean or anything towards Joy(and Joy in HHA is literally the sweetest character)

So yea, it is the HOA writers fault. They messed up with this, just like they did with a lot of other things by changing the original (side)-plot(s).
