If the height of the browser window is reduced to the point where the area available for displaying the scrollbar is less than that, the bottom part of the scrollbar is not drawn. Reproducible: Always Steps to Reproduce: 1. Load a page. 2. Reduce the browser window's height, keeping an eye on the vertical scrollbar. Assuming you've loaded a non-trivial page, you'll get a scrollbar at some point, even if you started without one. Actual Results: When the window's height falls below some value, the bottom of the scrollbar begins to disappear. If the window is shrunk further, more of the scrollbar goes missing. Expected Results: Whatever 1.7 does. I think it always draws the whole scrollbar, and doesn't let the window shrink below the size where a complete scrollbar can be rendered. I reproduced this bug with Orbit 3+1 1.5 MiK and Modern themes.
Please ignore the user agent string above. I forgot that I changed it using the UABar.

It too clips the scrollbar, but more sensibly - mostly. The scrollbar is clipped if: - no sidebar is displayed and the window height is reduced to the point where the thumb almost fills the paging region, or - the sidebar is displayed and the height is reduced somewhat beyond the point where the thumb disappears (!). That's the behavior with the Orbit 3+1 1.5 MiK theme. With Modern, it's a bit different. It appears that the height at which the scrollbar stops shrinking depends on how many sidebar tabs are displayed, and the thumb never disappears. Presumably the disappearing thumb is the fault of the Orbit theme. Anyway...the 1.7rc2 behavior seems reasonable to me. 1.8a1 always clips the scrollbar when the window falls below a certain height, regardless of the presence or absence of a sidebar, which I find surprising.

I don't think this is a duplicate. Bug 205566 takes issue with the behavior in versions prior to 1.8a1. This bug addresses a problem introduced in 1.8a1. It may be possible to fix both problems at once, but they cannot have the same origin, since one existed long before the other.
