Bug with Swain and Rek'Sai. [GAMEPLAY]

So when Swain drops his W (Nevermore) onto a Rek'Sai, if Rek'Sai uses her E (Tunnel in this instance) as the snare drops, she gets snared but is in her tunnel anyway instead of staying in place. Then by the time she gets to the other side the snare is over. This completely negates an ability when I believe it shouldn't, because Rek'Sai did indeed get snared, she just got to travel anyway whilst snared.

To reproduce simply launch tunnel as the snare drops. You will get snared, but travel anyway but being snared while moving is kind of uselessf
