Missing Texture if Item Is Made Unbreakable

Missing Texture Block Item Appears When Example You Use /give @a diamond_axe 1 1 {Unbreakable:1} it does not have the right icon this is a bug that needs attention since making adventure maps is impossible due to this since the damage bar should make it look damaged but it has to be done so its unbreakable from that point since axes are 5 time use on this project of mine so when you right click itl teleport you but then the damage bar would "Drop" to a lover level of so called "uses"
