`workingSetSort` is handled on `project/WorkingSetView.js#L599` to make the working set list update after a working set sort. This is required when using the sort methods from the context menu or the automatic sort.

I noticed that these working set changes event aren't used anymore to save the preferences, so when sorting individual items this event is now only used to disable the automatic sort, since updating the list doesn't make sense. So in this case, maybe the drag and drop function could just call a `WorkingSetSort` function to disable the automatic sort or use a new event. The current way still works but uses an unnecessary list redraw.
