Original Pull Request: https://github.com/microsoft/terminal/pull/2729

State: closed
Merged: Yes

Summary of the Pull Request

CLS calls two functions:

  • SetConsoleCursorPositionImpl()
  • ScrollConsoleScreenBufferWImpl()
    Both of these were not checking which buffer to apply to (main vs active buffer).

Now we get the active buffer and apply the changes to that one.

Also, we forgot to switch out of the alt buffer in the previous test. Added that in.
