When is Hecarim's E getting fixed?

I'm sure most people have been affected by this bug, but it's kind of annoying to me. Here's a video of it happening to DL. https://youtu.be/ClUGnKuUTG0?t=17m48s

There's no way that's how the champion is supposed to interact though, and I am shocked I haven't already seen something about it on Reddit.
