[Gameplay] Vladimir Sanguine Pool bug

Recently while playing as Vladimir, I experienced a bug with his Sanguine Pool (W) and its interaction with Thresh's Death Sentence (Q) and an execution attempt. As can be seen in the provided replay, beginning at approximately 29:40, the red team's Riven and Thresh attempt to kill me. In an attempt to deny gold I went for an execution, running through the top inhibitor turret and the nexus turrets. At this point Thresh attempts to hook me with Death Sentence, which I dodge with Sanguine Pool, before running through to the fountain turret and being killed. The issue however, is that Thresh is then awarded kill gold, despite his hook being dodged and 100% of damage taken coming from either minions or turrets. Fortunately this had no impact on the outcome of the game, however in other situations it's very possible that 300 gold would have a much greater impact, especially in the early game if this bug applies to any skillshots that miss on account of Sanguine Pool. No attempts to recreate the bug have yet been made, however I'll update this thread when they are. To any Riot employees reading, thankyou in advance for any investigation into this bug.
