px in media query

The doc says, `mediaQuery (Boolean) Allow px to be converted in media queries.` At first I thought this was a bug because my CSS properties in a media query were still being converted (which I didn't want). Both implicitly and explicitly setting this to `false` did not change the behaviour. Then I realised you probably mean converting `px` units within the query itself and not other properties that are descendents of that query. This could (a) be clarified in the docs and (b) perhaps a feature added to actually not convert descendent properties?
