Kha'Zix no Isolation bug [GAMEPLAY]

The bug is that Kha'Zix will lose his isolation whenever an enemy champion has anything that counts as a second entity next to them. Some quick examples of it would be a Thresh Lantern, a Syndra ball, Singed poison, Rek'Sai tunnel, Jayce gate.

And reproducing it is simple.

Step 1 as Thresh: Toss your lantern at your feet. Kha'Zix loses Isolation. Done. Step 1 as Syndra: Spawn a ball at your feet. Kha'Zix loses Isolation. Done. Step 1 as Singed: Start your poison trail. Kha'Zix loses Isolation. Done.

It appears every game of Kha'Zix that I have done when someone can spawn something. Here's an example from one of the top Kha'Zix players who made a video about it. https://www.youtube.com/watch?v=3t5LsoHBzXc
