@simon, Problem happens on apple safari even. 


as in the FrameView.cpp

PassRefPtr<Scrollbar> FrameView::createScrollbar(ScrollbarOrientation orientation) {

...
...
...
...
    // If we have an owning iframe/frame element, then it can set the custom scrollbar also.
    RenderWidget* frameRenderer = frame().ownerRenderer();
    if (frameRenderer && frameRenderer->style().hasPseudoStyle(SCROLLBAR))
        return RenderScrollbar::createCustomScrollbar(*this, orientation, nullptr, &frame());

As this part of code is executed, issue is seen in the safari.

Please find the attached testcase.

}
