Might not be a WebKit bug, you can test this too

flatpak run  --command=bash org.gnome.Epiphany.Devel

gst-play-1.0 --videosink glimagesink https://upload.wikimedia.org/wikipedia/commons/c/c0/Big_Buck_Bunny_4K.webm

and watch the video sink drop frames and emit warnings, the video is encoded in VP8.

On this old laptop I don't think 4K playback will ever work TBH.
