Why is Warwick not disabled? Has Riot said anything about it yet?

How is an already strong jungler allowed to be played with as ridiculous a bug as his ult being completely unstoppable? For those that don't know, WW ult is SUPPOSED to be unstoppable during his dash, then interruptible during the actual attack, but currently it is bugged to be unstoppable during ITS ENTIRE DURATION. Like, how is this seen as okay to exist and not just be disabled while they work on a fix?
