Pull-up fails for basic long clipped columns with no post-column or post-column-holder in-flow content in IE 8 beta 1

‘Long clipped columns’ is an important, industry-recognised technique for creating the appearance of equal height in (floated) ‘columns’. It works through giving the columns a large padding-bottom and a large negative margin-bottom, and then setting the column-holder’s overflow to hidden so that all column padding below the ‘pulled-up’ bottom border edge of the column-holder is clipped.

In this minimal test case the column-holder has an orange background. There is only one column: that with the red background. It is not floated.

In IE 8 beta 1 the column is not clipped, and scrollbars allow scrolling to the bottom of the column-holder’s unclipped content area.

In IE 6 and IE 7 the pull-up works correctly.
