Nasus Q going through Jax's E

Title says it all. To test take Jax press E and then get Q'd by Nasus. The damage hits and isn't bliocked (or ignored or w/e is supposed to happen). When it first happened in game I was like [zombie-brand-mindblown] , then after the enemy Nasus (good guy) helped me figure out the bug I was like [zombie-nunu-tears] .
