[GAMEPLAY] Elise spiderling takes up space on bench/team the same way a champion does

Not sure how to reproduce but I had an Elise in the game while playing TFT whose spiderling managed to take up a spot as if it was a champion. If I remember correctly, the glitch might be related to subbing Elise in and out but I'm not certain.

The spiderling had a red bar indicating it was an enemy. This created weird behavior such as my team attacking the spiderling at the beginning of the fight; the spiderling would still return though. When moving onto a different opponent (if I was the road team/had to TP to opponent's arena), the spiderling would stay behind; once again, it would still return.
