Sample window

WebKit sometimes renders garbage at the bottom of the page. I used the demo browser in Qt to check this, but happens in Qt Assistant, as well.

To reproduce:
1. Open a page that is long enough to have a vertical scrollbar. http://news.google.com will work.
2. Resize the width of the window so that the horizontal scrollbar appears.
3. Use the page down key to move one page down.
4. Then use the page up key. At this point, the horizontal scrollbar will disappear.
5. Now, use the down arrow key to move down. At this point, text that was originally in the area where the horizontal scrollbar used to be is now "stuck" there, and the rest of the page scrolls.

I'm not sure right now what Apple's Human Interface Guidelines say about this, but the "stuck" text is definitely a problem.

Also, I couldn't figure out what version of WebKit this is, but it's from Qt 4.6.2 release.
