preserving classes referenced in media queries #422
Description
I'm trying to use a media query to implement responsive mobile email layouts, so I passed preserveMediaQueries, but when using that with stripIdAndClassAttributes, classes referenced in the media query are not preserved. I'd like to remove all classes, except for those referenced in media queries. Is that possible with the current options? It not, could the classes be collected and automatically ignored or perhaps there could there be an option to retain some classes when using stripIdAndClassAttributes?
