Fishing bobbers can attach to endermen

The Bug

Endermen aren't supposed to be hit by projectiles, yet the fishing line "projectile" can hook him.

Steps to Reproduce

• Summon an enderman and obtain a fishing rod.
• Attempt to attach the bobber from the fishing rod to the endermen and as you do this, watch the behavior of the enderman closely.

Observed Behavior

Endermen can have fishing bobbers attached to them.

Expected Behavior

Endermen would not be able to have fishing bobbers attached to them, as fishing bobbers are considered as projectiles, and it's known that endermen attempt to avoid these when necessary, so it doesn't make much sense that they don't avoid fishing bobbers.
