Element#getOffsetParent returns a statically positioned element

Reported by Viktor Kojouharov | June 28th, 2010 @ 01:25 PM | in After 1.7

At least in Firefox 3.6, Element#getOffsetParent could return an element, which is statically positioned.

Specifically, getting the offset parent of a table cell descendant element returns the table cell 'td', since that is what the offsetParent of the descendant is set to. However, the 'td' is statically positioned, and should not be returned. This occurs if that element is statically positioned. If the element is relatively positioned for instance, it will return the correct ancestor. For this reason, Element#getOffsetParent() should skip offsetParent if it is statically positioned, and return the first ancestor with a real position.

Due to this, Element#positionedOffset returns incorrect offsets, which are based on a statically positioned table cells.
