Jumping in the Endportal whilest eating food makes you hear the eating sound the whole credits

I found this out when I ate a melon when I was working on the enderender and needed to gather some materials.
You can reproduce:
1. Goto the End and defeat the Enderdragon if not done yet
2. Give yourself the Hunger effect, or something so you can eat
3. Eat something and jump at the same time into the Endportal
4. You will see that the eating sound is looping.

I will post a video on youtube when I am at home again with record materials.
