[GAMEPLAY] Yasuo E bugs

I have encountered some bugs with Yasuo's E ability on two champions, Ekko and Veigar. Ekko: Yasuo can freely e through Ekko's W without being stunned. What happened was that I was ganked by Yasuo's jungler, Elise, and I casted W beforehand as I had my lane warded and I was able to stun Elise but not Yasuo as he E'd into me then kept using skills like normal. Another bug with Yasuo is that if his E's animation is in Ekko's Ult/R but he will land outside of Ekko's R range, he takes no damage as if he has reached the designated place as soon as this E was casted. Veigar: If Yasuo ults Veigar while Veigar is on the wall of "Event Horizon", Yasuo will not be stunned and he can e in and out through the walls of "Event Horizon" without being stunned.
