Sorting/Drag&Drop not working for select-options under Chrome

[thejanky]

Problem:

Using Sortable for options inside one or multiple optgroups of one or multiple select-objects works for Firefox but does not work while using Chrome.

When inspecting the behavior in Chrome i see that the selected element correctly gets the following properties: draggable="true" class="sortable-chosen"

but neither the visual indicator nor the resulting sorting does appear to work.

JSBin/JSFiddle demonstrating the problem:
