Possible Bug on Kayn Ult (Died while inside someone)

If you are able to see the webm I included with this report, you'll be able to see that after Akali came out of zhonya's I immediately used my ult to jump inside to avoid staying in the Miss Fortune ult. I sat in the ult for about 1.5-2 seconds then died before being able to pop out. Apparently I died to a Jinx auto. It would appear that what killed me is as I was in the Akali, who was standing near the tower, Jinx attacked the tower with rocket form and it seems that the splash still damaged me while I was in Akali. Which may be working as intended, since it's simply untargetability, but I figured I would fill out a bug report anyways. Thanks.
