mrtree layout always using DOWN

[geohuz]

const graph = {
    id: "root",
    layoutOptions: {
      "elk.algorithm": 'mrtree',
      "elk.direction": 'RIGHT',
    },
    children: nodes,
    edges: edges
  }

I've tried other directions, it always return DOWN layout. I've tried layered algorithm and it works fine.

Directions other than DOWN will only be added with the 0.9.0 ELK release or are usable with the ELK Java nightly build. In the meantime, I suggest using ELK layered.
