custom heads in chests do not /clone properly

When use the /clone command to clone a trapped chest
in this case.. a double trapped chest with custom named heads inside.

Not nessaciarly player heads but custom heads like this:

/give @p skull 1 3 {display:{Name:"Arrow Up"},SkullOwner:{Id:"478ca0c8-89b1-432c-932b-bb78eb462e06",Properties:{textures:[{Value:"eyJ0ZXh0dXJlcyI6eyJTS0lOIjp7InVybCI6Imh0dHA6Ly90ZXh0dXJlcy5taW5lY3JhZnQubmV0L3RleHR1cmUvNzNjZjE2NmE4MjZkODU1NDU0ZWQ0ZDRlYTVmZTMzZjNkZWVhYTQ0Y2NhYTk5YTM0OGQzOTY4NWJhNzFlMWE0ZiJ9fX0="}]}}}

Even though it renders properly in the orginal trapped chest,

when the chest is cloned, the heads apper as normal steve heads.

In previous builds of minecraft, atleast as far back as 1.9.2
this did not happen. This bug appers to be new with 1.10.2

I will attempt to replicate also in SP mode to see if it only affects the server.jar of minecraft or if it affects the minecraft SP game as well.
