There are lots of fancy position snapping and animations on apple.com product pages. After updating Epiphany Technology Preview to use WebKitGTK 2.39.1, they no longer work. Epiphany Technology Preview 43.0-87-g68837612b+, WebKitGTK 2.39.1, GStreamer 1.20.4
I also observed that, when visiting apple.com product pages, the terminal outputs multiple lines of `ERR: Display.cpp:1006 (initialize): ANGLE Display::initialize error 12289: Failed to initialize system egl`
After some testing, I've found that this issue is limited to certain product pages. For example, https://www.apple.com/apple-watch-series-8/ works, https://www.apple.com/imac-24/ doesn't. https://www.apple.com/ipad-10.9/ works, https://www.apple.com/ipad-pro/ doesn't. All the Airpods ones seem to work as well.
This issue can no longer be observed starting with 2.39.4 with the return of WebGL.
