Try loading: https://gitlab.gnome.org/GNOME/gtk/-/tree/main/gtk and attempt to scroll down the page. It won't work: the web process will appear to hang. Sometimes, the UI process will hang as well.

Does it happen with WEBKIT_NICOSIA_PAINTING_THREADS=0?

the web process of Safari and WinCairo also become almost unresponsive in the page. But, I don't observe UI process hang for them.

Ugh, this happens with GTK 3 as well. I had never noticed this until now, so I guess something must have changed on GitLab's side.
