Chromium WebScrollbarImpl's setValue() accepts values which are outside the document size and setDocumentSize() accepts values even when they are lower than the current scroll position. According to brettw's comment on the chromium.org bug (http://code.google.com/p/chromium/issues/detail?id=89367), the following should be the correct behavior: -If setValue() is passed a value > documentSize, then nothing should happen. -If setDocumentSize() is passed a size < the scroll position, then the scroll position should be capped at the document size.

It seems like rather than patching this in the Chromium-specific implementation, we'd want this behavior in the cross-platform code.

I thought that might be the case. I'll look into how that might work but any ideas/pointers are appreciated.
