Riot, what about Sion's 100% repeatable Q bug?

I see you fixed one bug with Sion's Q in the latest patch. How about the bug where he stops -- no, he interrupts -- his auto attacks after using Q?

Reproduce steps:

1. attack a turret
2. Press Q (charge or instant release, doesn't matter)
3. Your attacks will be interrupted after Q'ing (even if you immediately re-click the turret after finishing your decimating smash)
