I have some issues with this patch:

If the cursor is moved (by SetConsoleCursorPosition), the console actually
*should* scroll even if the scrollbar is being held by the mouse. The scrollbar
itself should not move, but this is actually something that should be enforced
by user32/win32k. (maybe open a new bug for this)

The GuiProcessWaitingMessages function can cause glitchy scrollbar behavior. A
scrollbar has its own message loop (see the ScrollTrackScrollBar function in
dll/win32/user32/controls/scrollbar.c). If you use your own message loop in the
midst of a scrollbar movement, it may happen that the user releases the mouse,
WM_LBUTTONUP is handled by this message loop rather than the scrollbar's, and
scrolling does not end as it should.
