Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1pre) Gecko/20090521 Shiretoko/3.5pre ID:20090521030957

So instead of resizing the vertical scrollbar when the pill (remove toolbar) button is clicked, it just gets shifted up (by what looks like the height of the toolbar).

STR:
1. Navigate to page that requires scrolling.
2. Press Pill button to remove toolbar.

Expected Behavior:
1. Scrollbar is resized.

(confirmed with new profile; presumably applies to trunk, but didn't test)

This doesn't happen with Firefox 3, so it's a regression in the last year...

Isn't this a dupe of bug 451641 ?

If bug 489891 is, then this is.

dup'd bug is blocking - clear blocking on this one.

Un-duping for a quick fix.

There's a number of cases that this approach gets wrong, for example collapsing a toolbar when the statusbar is hidden will cause the scrollbar to go under the resizer... but all in all it's better than before bug 56488 and fixes the special case of this bug (collapsing toolbars with statusbar visible).

I thought about adding a ContainsZeroSizedPoint method to nsRect, but I don't think it's worth it just for this one use case.
