Can't unlink "Item One" on an accordion control

To Reproduce:

1. Add an accordion control to a mockup


2. Set the Link dropdown for "Item One" to any other BMML file.


3. De-select and then re-select the accordion control.


4. Set the Link dropdown for "Item One" to the "No Link" option.


5. De-select and then re-select the accordion control.

Observed Behaviour

• Link dropdown for "Item One" now says "Broken: No Lin"


• Arrow indicating that the control has been linked remains on the first header of the accordion control.

Expected Behaviour

• Link dropdown for "Item One" says "No Link".


• Arrow indicating that the control has been linked is no longer shown on the first header of the accordion control.

Comments
This behaviour only occurs on "Item One". If there are two or more headers in the accordion and you follow the repro steps for any other item the drop down will correctly say "No Link" and the link indicator arrow will be removed from the associated header in the accordion control.
