Hi, I would appreciate if somebody could have a look at https://gerrit.wikimedia.org/r/139268 This is the second patch on a bug on CSSMin url() value remapping. Remapping was thrown off if the CSS contained comments containing curly braces. The fix just replaces all comments (except embed directives) with placeholders and re-inserts them after the url() value remapping. The first patch (https://gerrit.wikimedia.org/r/#/c/138286/) had to be reverted. It involved fixing the regex used for the url() remapping directly and would have worked, too, only the rule became too complicated, so preg_replace bailed out on large chunks of CSS. So, anybody up to it? Cheers, Stephan
