Sorry for the low quality, I'm not sure exactly how to reproduce the bug but it's either because Teemo flashed right as I Q'd or it's because the timer ran out right as I cast my second Q but Teemo avoided any and all damage from the kick in a potentially character breaking bug.

This is actually intended. This has been this way since the creation of Lee sin. Despite what you may think, the return is targeted to champion, but the damage is applied separately after Lee sin lands near his target. If you time the Flash while he is mid air, you can force him under tower to kill him (which I frequently bait to my advantage). It's about how you wish to time the flash -- air = follow, landing = dodge.
