Momentum scrolling stops abruptly before websites end
I am using the Epiphany Technology Preview (see attached screenshot). When I scroll with my trackpad, I have momentum scrolling in Epiphany. When I scroll fast so that the momentum is enough to reach the end of the website, then the scrolling stops abruptly (up to ~50px) before the real end of the website is reached. So it needs a second scroll to really reach the top (which is what I did in the video, that is not lag)
In my testing, the harder/faster the momentum scroll is, the bigger the gap is. This also happens with Epiphany 3.28 (which is what is in my OS repositories right now). I attached a screen cast showing the issue, so it is easier to understand:
I am using a Purism Librem 13 v2 laptop (I am not sure on the trackpad specifics, any command help for terminal output appreciated).
My operation system is the newsest Solus GNOME edition, currently running GNOME 2.28
EDIT: I reported the issue on the WebKit bug tracker: https://bugs.webkit.org/show_bug.cgi?id=193350
