Stylesheet and background image in ListWidget or ListView display issue

When using a stylesheet in a ListWidget with a background image, scrolling does not bring the picture up since the area does not expect to have to redraw it here.

Workarounds (for now): either use the background-attachment CSS property and set it to fixed, or modify the image to have a transparent area above.

stylesheet to apply to the widget in order to reproduce the bug:

background: url("/path/to/an/image.png") bottom right no-repeat;
