When you open the chat, it does not focus on text input

When you are trying to type in chat it does not always focus on the text input and does not let you type.

Steps to reproduce.
1.- In any world press T (or your binded key) to open chat
2.- While doing that do not move the mouse
3.- You will see you are able to to type
4.- Now do again steps one and two, but this time moving the mouse
5.- If you have the mouse on any part of the screen excpet above the text input you will not be able to type, and if you have it over the text input yes

Expected Behaviour.

• When you open the chat screen it will always focus on the text input
• If you press in any place of the screen out of the text input it will stop focusing on it so you will not be able to type
• If you hover the mouse over the text input it will not allow you to type, you will need to press on the text input to be able to type again.
