The Enderman can be hit by flame arrows and take damage also i think the arrow itsself may not do damage only the flame effect. The Enderman will be lit for the full period.

I'm not sure this is a bug.
It seems like the arrow hitting the endermen causes it to teleport, not to much that it teleports to avoid the shot.
Hopefully someone from Mojang will come and clarify this.
It's still set on fire because it gets hit by the arrow...
