In #4493 @miniksa pointed out that the state should be a member of SCREEN_INFORMATION rather than a static variable in WriteConsoleAImpl. Refer to https://github.com/microsoft/terminal/pull/4493#discussion_r389024806 In the current code base it's still in WriteConsoleAImpl though. https://github.com/microsoft/terminal/blob/d0ff5f6b5e7687c438e0a8b120280be307eda778/src/host/_stream.cpp#L1107 Since I closed the PR I just don't want this information to get lost.
