Issue Summary:

Icons defined for pages within a section in the jira:adminPage Forge module do not render in the Jira admin UI. This applies to both resource: references and absolute HTTPS URLs for the icon property. The main jira:adminPage icon loads correctly, but icons for individual pages nested under a section do not appear.

This issue is related to ECO-185, which was previously fixed for jira:projectPage, jira:globalPage, and jira:projectSettingPage modules. The fix does not cover pages within sections of jira:adminPage. A similar regression is also tracked in ECO-1089 for global modules.

Steps to Reproduce

1. Create a Forge app with a jira:adminPage module that includes a section containing multiple pages, each with an icon property (either using resource: references pointing to local SVG files, or absolute HTTPS URLs pointing to publicly accessible icons).
2. Deploy the app using forge deploy and install it on a Jira Cloud instance using forge install.
3. Navigate to Jira Administration → Apps and locate the installed app's admin page section.
4. Observe the icons next to each page listed under the section.

Expected Results

Each page within the section should display its corresponding icon next to the page name in the admin navigation.

Actual Results

The main app-level icon (app.svg) renders correctly for the jira:adminPage entry, but all icons for the individual pages within the section fail to load.

Workaround

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