Summary of the issue:
Petframe growth direction not tied to anchor or frame settings. I have raidframe manually set to go from right to left(since there is no other option to do this) and petframe on last left panel.. If raid has more than 5 pets, it'll create new petframe column on the right of existing petframe, leaving sometimes empty tiles between 2 full frame columns(full petframe and full player frame.
Expected behaviour: Frame growth/order tied to anchor and/or setting
Tell me what you feel should be happening. If existing petframe is at maximum set row limit(ie. 5 pets in 5 row limit), new petframe should appear according to the rule of frame order/growth/anchor. in my case it should appear on left side of existing petframe.
