[Gameplay] Super Minions stop spawning when inhibitor is still down- Not sure if intended or not

I've been noticing that Super Minions stop spawning before the inhibitor comes back up. One game, I was on the losing side (by a lot haha). Our mid and top inhibitors were down. They were destroyed at about the same time, within seconds of one another. Mid Super Minions stopped spawning, and there were normal minions in our base. Then, I heard the announcement, "your inhibitor is respawning soon". Well, this means that normal minions spawned well before this, because they had to take the time to walk all the way to our base. It was probably 3 waves of normal minions (or maybe more) that spawned before the inhibitor came back up. Top inhibitor was down, with Super Minions in our base. The announcement said, "your inhibitor is respawning soon". There was at least one, and probably two, more waves of Super Minions. The last wave to hit base was right after the inhibitor respawned, and this seems accurate considering their travel time, and they spawned while it was still destroyed.

This has been going on for some time now, and at first I was sure if it was intended and it confused me. After seeing that top does not do this, I decided to let you know here.
