The Bug

Dropped items only play the burning sound when thrown into lava if a player drops them directly in it. If the item touches anything prior to touching the lava, the burning sound won't be triggered.

Steps to reproduce

• Make a 2x2 lava pool
• Drop an item and it and make sure it's not obstructed by anything
• Make an ice lane leading to the lava pool
• Drop the same item in the ice lane
