In what order will enemies be attacked if the selected target dies mid-turn?

In Bravely Second: End Layer, in what order will characters attack enemies if the initial target of their attack becomes untargetable mid-turn (ie from dying)?

For example, suppose you are in a battle against enemies A, B, C, and D (in that order on the enemy roster list). You then command all of your party to attack enemy A. After a hit from your first party member, enemy A dies. However, there are still other attack commands from your other party members ready to go. Which of enemies B, C, and D will be selected as the target for those party members' attacks?

I would have assumed that the next enemy in the enemy roster (enemy B in the above example) would be selected as the target, but it doesn't appear to be the case. In fact, from my observations it looks like it is random - but I cannot be sure.

Is there a set order for which enemy would be selected? Or is it random? I would really like to know this since often there are situations where one enemy has a buff such as Reflect or Wall, and having the game choose to attack them without me specifically wanting to attack them would be detrimental.
