Okay, so by itself, and inside a single accordion... no problem with tabs. When tabs is located within nested accordions, the navigation background goes unstyled and locates itself randomly.

Example (launched): ​http://riftknowspot.co.cc/?p=61

Look inside the nested accordions, and the styling issue becomes apparent.

If you remove an item from a sortable while sorting and then call the refresh method it will cause the change event to fire at every mouse drag.

See this ​http://jsfiddle.net/NiGhTTraX/6mdZN/ for more details. When you start sorting the list, or drag a draggable over, the sortover event will fire. In the event function, I remove the last element in the list and call refresh . Notice that the change event is logged in the console on every mouse drag.

The problem seems to be in the _mouseDrag function. More specifically, the event is triggered at ​line 406.

Test: Popup datepicker, resize window, popup moves relative to the window not the content.

Response: I have seen that the 'page scolling issue' has been fixed by hiding the datepicker on scroll, maybe code can be added to hide the datepicker on viewport resize too?
