Using shift+tab to get in/out of the team overlay opens/closes your tab menu/ghost ingame. Using escape to get out of the steam overlay registers ingame, opening/closing the escape ui. This is extremely annoying when having a conversation while playing. Should be a very easy fix that will make active overlay users experience much more fluid. shift+tab issue will only happen if you hit shift and tab within relatively "fast" succession of each other. in the first clip i am only hitting shift+tab in the last clip i am only hitting shift+tab to get into the overlay, and escape to close it.
