Shaco Boxes do not proc items

Shaco's boxes do not proc spell thief's, ludens, etc. It happens every time and really would help with his kit. Teemo's mushrooms proc those items, Shaco's boxes should have the ability to do so as well. I love playing ap shaco specifically support and the lack of gold income from spell thief's really does hurt. It would be a really awesome bug fix for shaco. I don't have a link because this happens literally every time
