Problem with Xray macro/gadget "Overall Test Results" from Confluence

Steps to setup and replicate the Bug:

• Have an existent JIRA instance, with an Administrator User and a Non-Administrator user;
• Create a clean Confluence instance;
• When setting it up, on the Configure User Management screen, select the option Connect to JIRA;
• On the Connect to Jira dialog, fill the JIRA URL, fill a JIRA Administrator user, and proceed;
• When the Confluence instance is set-up, on Administration -> External Gadgets -> Gadget Feeds fill the JIRA URL and click Add;
• Restart the Confluence instance;
• When Confluence is restarted, login with Administrator user, create a Page, and add/setup the Overall Requirement Coverage and Overall Test Results gadgets - everything will work properly;
• On Confluence, logout, login with Non-Administrator user, create a Page, and add/setup the Overall Requirement Coverage and Overall Test Results gadgets - everything will work properly;
• On JIRA create a new Administrator user and a new Non-Administrator user;
• On Confluence, logout, login with New Administrator user, create a Page, and add/setup the Overall Requirement Coverage and Overall Test Results gadgets - everything will work properly;
• On Confluence, logout, login with New Non-Administrator user, create a Page, and add/setup the Overall Requirement Coverage and Overall Test Results gadgets - everything will work properly;
• On Confluence Administration, remove the Application Link between it and the JIRA instance;
• On Confluence Administration, add the Application Link between it and the JIRA instance;
• On Confluence, logout, login with the original Administrator user, create a Page, and add/setup the Overall Requirement Coverage and Overall Test Results gadgets - a prompt to allow will be displayed, allow, and everything will work properly;
• On JIRA create a newer Administrator user;
• On Confluence, logout, login with the newer Administrator user, create a Page, and add/setup the Overall Requirement Coverage and Overall Test Results gadgets - a prompt to allow will be displayed on the Overall Requirement Coverage gadget, but won't be displayed on the Overall Test Results gadget, and it will be unusable;
• After this, trying to add the Overall Test Results gadget with any new user won't work.
