The issue does not seem reproducible with WebKitGTK 2.30.2, nor with a
recent “trunk” build.

> HW: PC with i5-3570k/T470 with i5-7200u

Could you indicate which version of WebKitGTK is Epiphany using? You
can find it in the “About” dialog. I suspect it will be 2.28.x; in that
case, does the issue disappear when you use a newer version of WebKitGTK?
