HTML where figure will never reach the very bottom of the column

I have a multiple-column layout with a figure in the first column. In the attached HTML, the figure's margin-top is set to 11px and there's still room below the image. Changing the margin-top to 12px, however, forces the image to the next column incorrectly.

This bug – which only appears in Standards mode – was discovered when playing around with another (related?) WebKit layout bug that deals with Quirks mode:
