Frameset scrolling mistakenly scrolls the whole window.
In an HTML frameset, when the content of one frame is large enough for a scollbar to appear, scrolling that content causes the whole of the epiphany window to be scrolled and not just the frame concerned. I attach some very small example files that demonstrate the problem and some screenshots. To reproduce unpack test case files into a directory, open frameset.html in epiphany and scroll the right hand frames with the scrollbar. testcase.zip
