In the latest update the game automatically places keyboard focus into the search box when the UI is brought up. This applies in places including but not limited to:
End of mission UI
Dojo research UI
Faction vendor UI(s)
It is bothersome and unwanted. If I want to filter something, I'll put the focus in there manually. Otherwise it's just going to take some accidental inputs of movement/interact/spacebar and I'm going to have to delete it all back out to see things.
