Item Frame is dropped when used a Ender Pearl next to it.

You are using a modded client, ender pearls breaking item frames is normal (i think), but no proof endermen teleporting to frames breaks them

I was playing in my friends server, and a Enderman telported next to my house, and when I enter my chest room, all the item frames were dropped. So isn't a bug?

No. You're clearing using a modified client in those pictures.
