Issue Summary

After upgrading from 9.2.20 to 9.2.23, the Copy Space page is blank and nothing renders.

Steps to Reproduce

1. Install Confluence version 9.2.23
2. Create a space and navigate to Space Tools > Overview > Copy Space
3. Observation: The page shell and tabs load, but the content area is blank
4. (Optional) Repeat with a non-admin user; the behaviour remains consistent.

Expected Results

The Copy Space wizard (options, controls, and forms) should render within the content area.

Actual Results

The Copy space page is blank

Workaround

None identified. 

Observations

• Feature is functional in 9.2.20 but broken in 9.2.23.

• The bundled Copy Space plugin was updated from v19.2.52 (in 9.2.20) to v19.2.63 (in 9.2.23).

• atlassian-confluence.log shows no backend errors, and Browser Dev Tools show batch.js loading with a 200 OK. This appears to be a silent JavaScript execution failure in the new plugin version.

• Elements tab is UI for both versions:

• • 9.2.20 (Working): The <div id="copySpaceDetails"> contains the full UI structure (Form, H2 heading, and controls) and is expandable in the Elements tab.

• • 9.2.23 (Broken): The <div id="copySpaceDetails"></div> is entirely empty with no child elements, confirming the JS failed to mount the component.
