The Qt scrollbars have the ability to scroll directly to a certain position
when middle mouse button is used. This is often used e.g., also with rekonq.

Since rekonq has support for the so called auto-scroll when middle click it does not work fully anymore. A
crosshair appears and with some mouse movements I'm able to scroll left/right
and up/down in the webpage.
Though this scrolling is a good new feature, it removes the scroll-to-position
ability from the scrollbar. The "multiscroll" should only be toggled when your
mouse is on the webpage, and not when hovering over the scrollbar.
