background{0 0} becomes background{0}?

[futtta]

a{background:0 0}
becomes
a{background:0}

fix could be to change line 357 from
$css = preg_replace('/(background\-position|webkit-mask-position|(?:webkit|moz|o|ms|)\-?transform\-origin)\:0(;|\}| \!)/iS', '$1:0 0$2', $css);
into
$css = preg_replace('/(background|background\-position|webkit-mask-position|(?:webkit|moz|o|ms|)\-?transform\-origin)\:0(;|\}| \!)/iS', '$1:0 0$2', $css);

Shouldn't more regex control characters be escaped; not less?

Before:
$css = preg_replace('/(background\-position|webkit-mask-position|(?:webkit|moz|o|ms|)\-?transform\-origin)\:0(;|\}| \!)/iS', '$1:0 0$2', $css);

After:
$css = preg_replace('/(background|background\-position|webkit\-mask\-position|(?:webkit|moz|o|ms|)\-?transform\-origin)\:0(;|\}| \!)/iS', '$1:0 0$2', $css);

Had some issues with markdown, so some backslashes escaped ;-)

anyway, it now is how I meant it to be. questions remains whether webkit-mask-position needs escaping, but I'll leave that to @tubalmartin, he should know ;-)
