Traya's Isolate doesn't Isolate Ninth Sister's Taunt

its her patience unique:  "whenever this character loses taunt,gain taunt for one turn if an enemy has purge"

so when traya did isolate, she removed the taunt but it came back, then isolate was applied and stopped it from returning the next turn. this mechanic also happens with thrawn's fracture.

i don't know all the units but Bossk and Old Ben have a similar effect with their taunts
