The following components seem to have some JavaScript conflict issues:

- Drag and Drop
- Panel Popup
- Panel Positioned

For instance, with the Drag and Drop component, when I drop an item in the cart, on releasing the button I get a popup with "Error 500 -- OK" and on the server I see the following stack trace logged:
