Drag and Drop in jQueryUI mode disables after changing a column width

Hi,
I just found an issue with Drag and Drop columns when jqueryUIDraggable is set to 'true'.

If you change width of a column and then drag it to a new position, dragging will disable and attempts to drag a column again will end up in just selecting the caption.

You can reproduce that at your examples page http://ericmbarnard.github.com/KoGrid/#/examples
1. Go to "Grouping Example - jQueryUI"
2. Change the name column width
3. Drag and drop the Name column to the right
4. Try to drag any column again - dragging is disabled

So it appears that there is no solution for IE browser:
1. Native HTML dragging doesn't work in IE (see https://github.com/Knockout-Contrib/KoGrid/issues/187)
2. jqueryUI dragging has this bug

Start with the Grouping Example - jQueryUI on the KoGrid examples page and reproduce the sequence: resize the Name column, reorder it, then try dragging again. Inspect the jQueryUI drag-and-drop behavior around column resizing and compare the IE limitation noted in issue 187. Done means columns remain draggable after resizing and reordering.
