Renamed items in item frames don't show their name

If you don't know what I mean, in the 1.7 update on the PC version a change was made where if you take a renamed item (e.g. sword renamed "slayer of the undead") and put it inside an item frame, the name of the renamed item shows up above the item frame itself, almost like a name tag. Currently, this feature is not working correctly on the console edition, despite working just fine on the PC version and Mcpe.
