The Sortable Portlet Demo is buggy

Portlet Demo

Adding a portlet to the last row of a column can cause the portlet to be added as the second to last element before it is added as the last element.

Steps to Recreate

1. Navigate to the Sortable Portlet Demo

2. Drag the last portlet from the third column over to be the last element of the first or second column

3. Notice how the portlet being dragged attempts to be the first element of the column your dragging it to instead of the last

4. The portlet can then be added as the last element if you move it up to that location and then down to where you want it.

The bug is in #3 of the steps to recreate.
