Title: Issue with multiple scrollbars (IE)

The issue appear when there are 2 scrollbars in the page.
The main scrollbar isn't added automaticaly in $target.offset().top for IE (version < 9)
So when I try to select an interval, the selection is shifted by the size of the first scrollbar.

Add to the current offset, the scrollTop value of window.document.documentElement fix the issue.
