This is not the correct fix. Simply reverting a patch because it broke
an application without understanding why is not the right way to go.

In this case, some applications
(http://bugs.winehq.org/show_bug.cgi?id=13459) specify the
DOCHOSTUIFLAG_SCROLL_NO flag to specifically not show any scrollbars.
In the case of bug 13459, the intro page does not render correctly if
scrollbars are shown (and on Windows you don't see any scrollbars).

What is the behaviour on Windows? Can you explain comments 3 and 8?
