[GAMEPLAY] Vel'koz W animation still plays when blocked by Braum E

Just played a ranked game as arclight Vel and I threw my e w at a braum as he threw up his e. The sigil showed on the ground behind him and he took two passive stacks, but when the sigil erupted, he (and his nearby teammates) took no damage/passive stacks.

Took it to a custom game with a friend to recreate and each time I w'd the braum with his a up the full w animation played, but was only affected by the first instance each time. Only tested with Arclight, and unknown if yasuos wind wall does it too.
