Jhin either has an annoying mechanic or a major bug (maybe).

This has happened quite a few times to me. I go to last hit something and it dies just before the auto goes off. Normally this just should cancel the auto and immediately fire on the next target like it never happened. But it seems Jhin ether does not have this, or it is not working properly, and I end up having the full auto CD + some before I can finally get a shot off or cast an ability. It is noticeably longer than normal too. Like 1.5-2 seconds long. This is a huge issue for champs like Jhin who have very set and limited time windows where they can deal damage. That 1.5-2 seconds can be the difference between getting every minion or missing most of a wave if you had primed it for a nice Q chain.

Has this happened for anyone else? Is this intentional or a bug?
