As far as I know the Frederik Hendrikplantsoen connects to the Frederik Hendrikstraat here. There are no street signs that claim otherwise. The road looks a bit like a triangle, and the southeastern part (consisting of two lines) has no name in OSM. Maybe you can redraw the line (so it becomes a single line), give it a name and add the relationships with the tram lines again? I can try this as well, but I started contributing to OSM just yesterday and I'm not entirely confident with the editing interface yet.
