Screencast showing kinetic scrolling working intermittently

Starting from WebKitGTK 2.39.1 in Epiphany Technology Preview (GTK 4), kinetic scrolling with a touchpad works intermittently. One scroll and the scrolling decelerates gracefully, another scroll and it abruptly stops. It worked much more reliably in WebKitGTK 2.38.x (GTK 3 stable and GTK 4 Tech Preview). It works approximately 8-9 out of 10 times.

I've seen that happen before, but I'm not able to reproduce it atm - even on that specific page.

Note: this issue persists as of WebKitGTK 2.39.4

Another note: kinetic scrolling doesn't seem to work at all on Reddit popups, i.e. when clicking on a post in the home page.
