For an example follow these steps.
1. Go to eoss.co.nz
2. On the accordion click the first 2 shown list items
3. Select the open tabs or the list items from the accordion and they will match
i.e. selecting the list item will activate the tab and selecting the tab will
highlight the matched list item. Do this as much as you like to convince yourself the functionality is as intended.
4. Drag and swap the tabs.
Selecting the tabs will still select the correct list item due to the JQuery selector but selecting the list items now select the alternate tabs.
5. Expand the next accordion and select the first list item. This will stay in sync between the list item and the tab, but the first two tabs will still be in the wrong order.
