Issue Summary

"Confluence Page Viewer" gadget present in Jira 10.3.x fails to render images like previous "Confluence Page" gadget present in Jira 9.12.x

Steps to Reproduce

Instance

• Jira v10.3.7
• Confluence v9.2.4
• Draw.io plugin v14.2.3

Steps

• Create Confluence page containing a drawing using the "draw.io" plugin
• Establish an application link between Jira and Confluence instances
• add the "Confluence Page Viewer" gadget to a dashboard and configure to view above page
• view the render page

Expected Results

Expect the image on the Confluence page to be rendered in the gadget as it did in the previous Jira 9.12.x "Confluence Page" gadget

Actual Results

The page ins rendered without the "draw.io" image.
The difference between old 9.12 gadget is that it would contain both CSS and JS script contents to render the image. The newer 10.x gadget includes the CSS but fails to provide the JS script content. The missing script is the reason the image does not render

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
