You cannot move (by clicking directly) over Hextech Sion's dead body

When Hextech Sion dies truly (after his passive), you cannot click on the lower part of his body. At his chest and lower, even lower than his feet, you can't click. If you try to, nothing happens, and you won't move. But, you can ping him. If you ping "click" on his body, as you would on a turret or an alive champion, a ping will appear (once again, his lower part of body).

This becomes quite the issue if you are trying to juke around an alive enemy where there is a dead Sion body lying around; your character won't move when you "accidentally" click on Hextech Sion's lower dead body, making you stand still until you click somewhere else.

Note: I don't know if this applies to Sion as a whole, or just the skin Hextech Sion.
