1. A one-sentence summary of bug: The Wilderwings mechanic to save fireworks can be manipulated to give free infinite rockets.

2. Priority to fix? Low

3. Which server?: Tree servers

4. Steps to Reproduce: Setup a soul sand bubble column so the player can enter and stay in elytra fly mode by floating in the bubble column, then have a door infront of the player that they can spam click while suspended in fly mode.

5. Expected Outcome: No rockets would be "saved" by the Wilderwings because none were actually being used.

6. Actual Outcome: The server thought I was using rockets and gave me more rockets repeatedly, essentially enabling an infinite source of free rockets. 

7. Proposed Fix (Optional): Make it so the server recognizes when the player is clicking a container or flippable block while a player is in elytra mode, and does not try to save rockets when this is happening.

8. Notes (Optional):

9. Screenshots (Preferred):

Thanks for the bug report xHerobrine! Just fixed this in code. Pushing now for next reboot.
