Objects are clipped by the browser window when the browser is resized to be very small.
When scroll bars are finally displayed the object is still clipped so the entire object is never completely displayed.
Scroll bars are properly displayed within the browser window when the browser is resized to be very small so the object is completely displayed without clipping.
Object positioning does not appear to be affected by "position: relative".
Horizontal scroll bar is not displayed until the object is clipped by an amount equal to the size of the scroll bar.
