Epiphany on Arch Linux, webkit2gtk 2.16.6-1 GNOME bug here: https://bugzilla.gnome.org/show_bug.cgi?id=785646 When I read an article on https://aeon.co , I cannot use keyboard shortcuts to scroll down. At the top of the page, Space and PgDn usually work well 2-4 times, after which either of them suddenly jumps straight to the end of the page. This might happen on some other sites, however I think I've only encountered this behavior on aeon.co. Other browsers work correctly on this site. On epiphany, Aeon has behaved like this for at 2-3 releases. I have no idea how the site is built, or why Firefox and Chromium survive it just fine.
