CSSMin doesn't need to generate double rules for IE<8 when embedding SVG files. IE<8 will not load SVG images anyway, so this just wastes space.
This if() in CSSMin.php probably should have a test added for SVG MIME type.
if ( $embedData && $ruleWithEmbedded !== $ruleWithRemapped ) {
return "$ruleWithEmbedded;$ruleWithRemapped!ie";
} else {
return $ruleWithRemapped;
