Shaco q getting revealed by pink wards

In a game i just had, a Sivir was able to attack me while i was stealthed by Shaco q. When i asked her she told me i got revealed when i walked into pink ward range. I checked a replay from replay.gg and it was exactly like that despite Shaco q being labeled as Invisibility, which is not being revealed by Pink Wards.

Can provide more info or a link to the replay if needed.

I'd like it to be fixed for obvious reasons >.<

Greetings
