Magic Earth actually hasn't updated it's OSM data yet so I was still able to replicate the old behaviour. It handles that way you linked fine, perhaps because of the longer junction arms?

I don't really like editing for the router in major cases (like changing an entire road classification), but this seems fine. At the same time though if there's other cases it might just be best bringing it up to the Magic Earth team to see if they can fix it.

It certainly seems strange to me, because surely routing by this junction doubles the length travelled? I do wonder if putting give way nodes would help.
