[GAMEPLAY] Zac's E cancelling itself

Zac's E cancels itself at awkward angles closer to himself, instead of slingshotting himself as close as possible to the target mark. At correct angles closer to his indicators, this isn't a problem. When players try shooting Zac further and further outside of his indicator, it becomes increasingly likely that the ability will be cancelled and put on cooldown altogether. I couldn't find the exact angles, but it is easily reproduced.

1. Load up Zac into the practice tool with Auto-Refresh Cooldowns.
2. Use Elastic Slingshot first on the fringes of the indicator.
3. Steadily move your Elastic Slingshot's further and further outside of his indicator until bug is reproduced.

I understand that if players were to try to shoot themselves backwards it would cancel, but there were several times when I tested this that I was able to cancel Zac's Elastic Slingshot without meaning to. Even if it isn't a bug, this should be a quality of life improvement.
