How to Reproduce
Open lan/multiplayer world
Press "P" to open Social Snteractions Screen
Press "Tab"
Click anywhere on the screen using mouse
Notice how button you previously selected using tab is not selected you cant use tab anymore
Can confirm.Note that you need to click in "empty space" to reproduce this bug, i.e. not on a button. Just noticed that the report has already been marked as cofirmed
