BUG: scrolling a hover pop-up scrolls the entire page along with the pop-up

If there is a long page in a hoverover then scrolling works weirdly, the hoverover is scrolled along with the main page. Moreover, if the hover page is too long its content may spill off of the page and being inaccessible.

I would find it nicer if there were independent scrollers.
