HT - Taunt never goes away if breach is up?

So I was in fleet arena attacking someone with hound's tooth. That HT put breach on one of my ships. But, I was using Millenium Falcon to attack it. On it's basic it is supposed to debuff attacks. I can understand if you have it maxed out that HT will regain taunt for one turn if an enemy ship is breached. But, does that mean it will keep taunt forever? I hit it 8 times (due to assists) with MF's basic and other buffs were removed, but it's taunt stayed up.

Just curious if that's actually working as intended or not. There's still the other bug with HT so I don't know if it's a bug or WAI.
