Viewing a friends name while they play taliyah

I have encountered a client based bug where i hovered over my friends profile in the friends tab. He was playing a game where he played the champion taliyah and where it would say (in game) summoners rift, twisted treeling or whatever he was playing at the time, it only said (in game) Taliyah.

I don't know if this happens on just EUNE where i play or other servers and neither do i know of any way to replicate the bug as i have only seen 1 of my friends play the champion 1 time

Just a minor bug but a bug nontheless
