g_state
Set on your own domain by the Sign in with Google client library. Records whether the visitor has dismissed the One Tap sign-in prompt and for how long it should stay hidden, plus the time the library last loaded and a browsing session id used for the same purpose. Sites that pass a custom state_cookie_name will see that name instead.
