Incorrect descendent CSS output

[Harbs]

The following CSS:

TitleBar CloseButton
{
        width: 16px;
        height: 16px;
        margin: 0px;
}

is output as:

.TitleBar CloseButton {
        margin: 0px;
        width: 16px;
        height: 16px;
}

Instead of:

.TitleBar .CloseButton {
        margin: 0px;
        width: 16px;
        height: 16px;
}

I think this is a bug.
