Currently, disabling the statusline with `settings set show-statusline false` leaves LLDB in a broken state. The same is true when trying to toggle the setting again. The issue was that setting the scroll window to 0 is apparently not identical to setting it to the correct number of rows, even though some documentation online incorrectly claims so.
