[GAMEPLAY] Ingame chat adds lots of ^ when chatting with custom trinket key set

We just found out that if you change the trinked key from "4" to the key left to 1 (on our keyboard layout it's "^", but the client shows "´"), the ingame chat adds lots of ^ when you try to write something (see attached screenshot).

The first line in chat was written with the settings of the left panel. The second one with the settings of the right panel.

To reproduce the bug:

1. Open Options
2. Change trinket key to the key left of "1" (in our case it's the °/^ key, but lol shows `).
3. Write something in chat

So if you encounter this bug, just change the trinket key back to the default (4) until it's fixed.

This works on every client of our team. We're using League of Legends 4.21.14_12_08_11_36 in English / EUW
