scrollbar can be hidden by the miniplayer
in list/grid mode, when the miniplayer is visible the scrollbar of the the main view can be hidden by the miniplayer.
the reason is because the mainview is visible through the miniplayer for cosmetic effect, to achieve this an empty padding area is added at the bottom of the list and grid view, but the scrollbar of the view fill the height of the view, so it might be partially occulted by the miniplayer.
The expected behavior is that the vertical scrollbar should fill the available space, from the top of the view to the top of the miniplayer (when visible) or to the bottom of the view when there is no miniplayer
