Issue Summary

• Exporting a Confluence page to PDF fails or hangs indefinitely at 0% when the page;
  • Contains a high volume of Expand macros, or
  • Large amounts of content nested inside Expand macros (such as images, nested macros, or large tables).
• During the export process, Confluence expands and renders all hidden content concurrently, causing the task to exceed the backend processing timeout and fail.

Steps to Reproduce

1. Create a Confluence page containing numerous Expand macros (or Expand macros holding extensive nested content/media).
2. Attempt to export the page to PDF
3. Notice the export remains at 0%

Expected Results

• All Expand macro content renders completely and the PDF file downloads.

Actual Results

• The export progress remains stuck at 0% until the backend processing timeout is reached, causing the export to fail.

Workaround

• Split the page to reduce the total number of Expand macros on the page.
• Move heavy content (large tables, nested macros, images) out of Expand macros or split the content across multiple sub-pages.
