Solved Interaction event is not fired while holding a non-standard mob-egg.

The PlayerInteractEvent is not fired if the player supposed to be causing it is holding a non-standard mob egg, for example an Iron Golem egg (383:99).
I think this is because of vanilla Minecraft's protection against spawning invalid entities corrupting the map.
Is there any workaround for this problem?

Thanks

Edit: Sorry, my bad. The event is fired.
