the two files attached could be used to create a simple add-on showing the problem.
At add-on installation, right or left clicking on the widget icon will result in a message in the console.
After 6 seconds, the contentURL property of the widget is changed (using setTimeout). After this change, clicking on the widget icon does not show a message in the console.
