Alt screen separate scrollback
Tests whether the alternate screen buffer maintains its own separate scrollback, independent from the main screen's scrollback. Most terminals do not provide scrollback in the alternate screen — full-screen applications are expected to manage their own scrolling. Some terminals (like Kitty) offer configurable behavior for alternate screen scrollback.
