Description Kdwk 2022-11-22 06:29:16 PST

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.
