Simple fix (which causes test regression)

I tried to fix this bug, but I'm facing some difficulties on it. I've got a
simple fix (attached) but this causes a test regression that is difficult to
handle.

LayoutTests/fast/dom/background-shorthand-csstext.html fails, becuase div1's
background property value is serialized to "repeat-x, white repeat-y".
Apparently this should be "white repeat-x, repeat-y". However, WebKit CSS
parser does NOT accept "background: white repeat-x, repeat-y;" as a valid style
sheet declaration, so we can't do this. For now, I can't find any resolution
that satisfies both CSSOM spec and WebKit parser. It seems too difficult for me
to hack the CSS parser (at least for now).

By the way, according to CSS2, the value "repeat-x, repeat-y" for
background-repeat property is invalid (you can use "repeat" for this purpose).
I assume that this is a WebKit extension, but I'm not sure it really is.
