Hi Eric, in the current Safari TP 139, I'm seeing currentTime jumping back to 0 when seeking for live streams like so: timeupdate – 7193.6532422809705 set currentTime – 7173.88901530305 seeking – 7173.889107168126 timeupdate – 7173.889107168126 timeupdate – 0 seeked – 0 timeupdate – 0 timeupdate – 7173.988310672026 (correct timeupdates continue) timeupdate – 7174.13682652897 Is this related to this issue, or should I fork it as a different bug?

The Windows test failures: - js/function-apply-many-args.html - svg/animations/animate-keytimes-crash.html - svg/as-image/img-zoom-svg-stylesheet.html are unrelated.
