[Biwin John]

New submission from Biwin John:

The sidebar on the documentation pages ex. https://docs.python.org/2/library/collections.html vibrates/flashes on mouse wheel scroll. 
The sidebar with class sphinxsidebar, works okay when scrolling with the scrollbar, Firefox but not with mouse wheel on Chrome.


please consider fixing it.
