I am not sure whether this is something fixed or not? But all browsers are outputting same. Thanks! 1892695 4 ap 2022-08-20 14:23:46 -0700 This still reproduces as before - WebKit and Blink get "initial", Gecko gets "medium". Blink has a patch posted for this in 2021, not landed yet. The test isn't quite right, it lacks ".style".
