Cant command pet to cast spells or attack on stealth targets

[Lelol]

What is the bug?
Can't command pet to cast spells or attack targets that are stealthed but are close enough(or arena eye) for the player but not the pet to see.

What kind of bug is it? (Quest, Class, Spell, PvE)
Spell/Pet/Mechanic

How can you reproduce it?
Get on a warlock, summon felhunter, duel a rogue, place your pet 10-20 yards away from you, have to rogue stand right next to you, target the rogue and try to attack him or cast spells with the pet. Pet will refuse to.

Please describe, in detail, what is suppose to occur when this bug happens:
Pet should be able to attack/cast spells on the target

Please describe, in detail, what happens when it bugs up, and how it's malfunctioning:
The server seem to think that the pet needs to be able to see the target for it to cast/attack it.

Evidence providing proof of bug:
Couldn't find any videos of this but I haven't looked much either.. However I am 100% sure it was working like this in TBC since I played human warlock myself. and remember doing this in TBC & Wotlk
