Entities score's are useless in tellraw.

1. /summon ArmorStand ~ ~ ~

{CustomName:"test"}

2. /scoreboard objectives add scoreTest dummy

3. /scoreboard players set @e[name=test] scoreTest 1

4. /tellraw @a {score:{objective:"scoreTest",name:"@e[name=test]"}}

5. The message is : "" but it must be : "1"
It works for players but it doesn't works for others entities.
Help me please !
