[INTERACTION] IVERN BUSHES WITH SUMMONER'S RIFT, TWISTED TREELINE, HOWLING ABYSS

If you look at this video, you see some serious issues with Twisted Treeline Map, and bushes under turrets. Could someone with PBE Access test that out and see how it works with Ivern's W. If it works differently why not fix Twisted Treeline? Could someone share results?
