### Description of the bug

On first connecting to the server if you attempt to open an input box like say/looc/ooc etc. It'll lose focus. After this first time I doesn't happen again until you reconnect.

EDIT: Just for clarity this will occur if you sit in the lobby and then spawn in and go about your stuff for 5 minutes and then try to say something.
### What's the difference with what should have happened?

It shouldn't lose focus for mysterious reasons

### How do we reproduce this bug?

1. Join the server
2. Attempt to trashtalk in OOC
3. Cry because you have to click the box or open the ooc say again
