Some Monk attacks can't break destructibles

1. Create a Monk and advance him to the quest "The Legacy of Cain."
2. Enter the Cathedral and locate a destructible gargoyle-style statue.
3. Using the Hold Position key while standing in range of the statue, execute a melee attack.
4. ---> The animation plays as normal but the statue is not destroyed.
5. Using the Hold Position key while standing in range of the statue, use the Fists of Thunder skill.
6. ---> The animation plays as normal but the statue is not destroyed.
7. In the same position, use the Lashing Tail Kick skill.
8. ---> The statue is appropriately destroyed.

Additional information: The melee and skill-based attacks of other classes are sufficient to break these statues (Barbarian melee hits, Demon Hunter crossbow shots, etc.). It definitely seems to be buggy that the mighty Monk is stymied by mere stone.
