Note that -webkit-canvas has the same problem.
in CSSCanvasValue::image

There are a few options.

1. add the canvas and gradient as clients before asking for the images. I
expect this wastes memory in the case where a canvas/gradient is set on the
body, then removed.

2. remove the asserts. Since gradient calls getImage and it causes the renderer
to be added as a client I don't think it is a big deal, but I didn't
investigate much. I didn't try this with canvas.

3. Work out why body elements are not doing the right thing with
updateFillImages from RenderObject::setStyle, which is where other elements add
gradients and canvas as clients.
