Details

See comment in https://github.com/servo/servo/blob/ed5485ed18535a1de9401c7c9499be26292e76fc/components/style/gecko/media_queries.rs#L134

Gecko support emulating random medium, which takes effect via nsPresContext::Medium() [1]. However, Stylo doesn't use that, but instead read nsPresContext::mMedium directly.

Also Servo doesn't support random medium either because it uses enum for medium type.

Test layout/base/tests/test_emulateMedium.html checks this functionality, and it seems to me devtools may depend on this.
