See also https://bugs.chromium.org/p/chromium/issues/detail?id=1138859 If you run: window.matchMedia('(max-width: 100px) and (max-aspect-ratio: 1/1)').media You get back: (max-aspect-ratio: 1/1) and (max-width: 100px) Instead of the expected original order. Per https://drafts.csswg.org/cssom-view/#mediaquerylist-media -> https://drafts.csswg.org/cssom/#serialize-a-media-query-list: > Serialize each media query in the list of media queries, in the same order as they appear in the media query list, and then serialize the list. Seems like Gecko is correct and the order shouldn't change.
