~onDungeonStart doesn't fire when called from a Furniture's FurnitureSkills

~onDungeonStart doesn't seem to fire when called from a Furniture's FurnitureSkills.

TestCase:

1. Create Furniture with FurnitureSkills 2. Define a Skill to call when ~onDungeonStart i.e.

  - setBlock{type=GOLD_BLOCK} ~onDungeonStart @self

(i've tried with targeting @furniture and no target) 3. Place Furniture in dungeon editor via /md edit dungeon (i used the starter room of a procedural dungeon in my case) 4. Save Dungeon with Furniture in it. 5. Play Dungeon 6. Furniture doesn't call the mechanic
