Tavish Stormpike Hunting Shroud broken

I’ve been doing PVP and every time I proc the bear from bear trap (bear trap 1) it summons a 3/5 bear with taunt rather than the 5/5 the ability reads with the Hunting Shroud 1. So either 1) Hunting shroud is bugged and isn’t giving it’s attack to the bear for some reason, or 2) it’s poorly worded and is meant to give the attack only if it survives. Either way it’s very frustrating.
