Seems fine, but is there a better way to get the mouse position of zoomed content?

MouseRelatedEvent.h has:

    // Page point in "absolute" coordinates (i.e. post-zoomed, page-relative coords,
    // usable with RenderObject::absoluteToLocal).
    const LayoutPoint& absoluteLocation() const { return m_absoluteLocation; }

That ultimately uses:

    float FrameView::documentToAbsoluteScaleFactor(Optional<float> effectiveZoom) const
    {
        // If effectiveZoom is passed, it already factors in pageZoomFactor(). 
        return effectiveZoom.valueOr(frame().pageZoomFactor()) * frame().frameScaleFactor();
    }

As opposed to the current `InspectorFrontendHost::zoomFactor()` which only does the page zoom:

    m_frontendPage->mainFrame().pageZoomFactor();

So, what is `frameScaleFactor` and what is that / should that be taken into account here?

r=me though since this can't be worse then what we currently have
