Screencast showing GIF not loading on main page but only when post is opened

On https://www.reddit.com/r/memes/comments/12eog2u/crossgenerational_meme/, the GIF can load when the post is opened but not on the main page itself.

Tested on WebKitGTK 2.40, Gnome Web 44.1

I suppose https://www.reddit.com/r/memes/ would be the link for reproducing the bug with the GIFs not loading, but actually they do load for me when I view that page....

Loupe the image viewer is unable to display the GIF

Loupe the image viewer reports that the GIF has a malformed GIF header and is not able to open the file. EOG could not open the GIF either.

However, the GIF was able to play when Epiphany opens the URL I downloaded the GIF from, https://preview.redd.it/6nv9i3ucahsa1.gif?format=mp4&v=enabled&s=2488375b3a897f877b62c50d40bd123b738ef883

Well there's a hint right there in the URL. It's an MP4 with a .gif file extension for some reason.
