[Description] Browsenode lookup is often used to find the top seller in the browsenode category. When the browsenode is at the top of the category, the top sellers list is inaccurate. [Impact] Do not use the top root browse node in a category to find top sellers. The workaround is to use one of the child browse nodes with the TopSellers response group. [Issue] 
The BrowseNodeLookup operation often returns inaccurate results for top sellers when the browse node in the request is the root node of a category.
