This is spun off from Bug 914251

Autoscroll does not work as expected.

      html, body {
        width: 100%;
        height: 100%;
        overflow-x: hidden;
        overflow-y: scroll;
      }

breaks autoscroll.


Steps To Reproduce:
1. Enable autoscroll from preferences if necessary
2. Open attached sample html
3. Attempt to autoscroll

Actual Results:
Outer scroll box(html) is not scrolled

Expected Results:
Outer scroll box(html) should be scrolled when inner scroll box(body) touched the top/bottom.
The behavior should be like overflowed textarea in this page.

This is not true...

But in the case of comment#0, I think outer scroll box should be scrolled because last line of the content is cut off.
