Sylas name displayed as the name of the champion whos ult has been stolen

If Sylas steals an ultimate where he changes into a champion either briefly (e.g. Galio as shown) or for a longer time (e.g. Shyvana) when he is in their form when typing in chat his name is displayed as their name.

Reproducing:

1. Steal an ultimate of a champion where sylas changes
2. When in their form type anything in chat

This might be intended, but I found it a bit confusing when I saw a 'shyvana' on my team talking to me when she was on the enemy team.
