Issue described in #5945.
Unit finishing the order such as walking, will reach destination and if attacked, imediately reacts to the attacker.
Hovewer, more desireble is for unit to look around since entering idle state and pick the target if any using preference and then react to attacker.
This issue rised up after finding of new targets have been moved from enter to timer to avoid infinite loops after alwaysenterstate logic removal.
Only downside here is unit will receive few hits before reacting as we are waiting to the timer first. This happens only if unit goes idle.
