Looks like this whole block can be nuked.

The fails started because of a version change in jQuery is picking this up as an error.

We always were calling draggable destroy on an invalid object, previously this would just early return but now crashes.

The if statement is never going to be true.

I made enough code to make it work, passing in the correct draggable element, and it causes this to not be draggable after a content editable.

So far, best I can tell. I say nuke it though.
