[Bug] When using tricks of the trade from stealth on Brann in Delves, Dealthstalker's Mark falls off target

To reproduce:

  1. Go into stealth
  2. Cast Tricks of the Trade on Brann (or other? Have only tested with Brann)
  3. Ambush target
  4. Watch in sadness as Deathstalker’s mark does not apply, or applies and then immediately falls off.

If I ambush from stealth and then use tricks of the trade as me second ability, Dealthstalker’s Mark acts as expected and stays on the target.

Not sure if its related but brann likes to attack things that you havent pulled which sometimes bugs out the mobs, where they pull and reset extremely quickly. The effect that ive noticed this has, is that my perma tricks (trickster) on brann doesnt divert threat to brann when I attack that mob
