Dear Maintainer,

After upgrading to 2.52.3-2~deb13u1, I have found that browsing to
https://bsky.app in epiphany-browser will fail to render any of the posts.
After a while the browser will say the page is unresponsive. When viewing
Bluesky posts through gnome-feeds *some* posts will render, others will not. It
seems that having an image in the post causes the same behavior as in
Epiphany/Web.

When this bug occurs, WebKitWebProcess will peg one of my cores to 100%.

Reverting to 2.50.4-1~deb13u1 fixes the issue.
