Arcanist pet target not resetting while steady

Time: N/A
Frequency: Always
World name: Diabolos
Character name: Carmilla L'fanu
NPC name: N/A
Monster name: Any
Class/Level: Summoner Lv. 50 (also happens with Scholar)
Party or solo: Solo
In-game time: 12:24 ET (Any)
Area and coordinates: Any map
Steps:
1. Set your pet to Sic or Obey
2. Grab aggro from a monster
3. Change your pet stance to Steady
4. Run away from the monster until it resets
5. Set your pet back to Sic or Obey
6. Grab aggro another monster anywhere in the same map
7. Your pet will run away to attack the first target, no matter how far it is, often causing it to automatically withdraw

Note: This also happens if the pet was already set on Steady before grabbing aggro.

Note 2: I believe this started around a month ago or less, before it used to untarget whatever was attacking me as soon as I set it to Steady stance
