Issue Summary

When exporting to PDF pages that contain iFrames with Figma designs or Graphy charts (public content) the exported PDF does not display them properly.

The PDF seems to be generated before the external content is finished loading.
For Figma designs, the result is a black box with some metadata (title, last edited) from the target document but the actual content is not displayed.
For Graphy charts, the result is a white box with what looks like a snapshot of a partial loading spinning icon.

Apparently, the 30-second threshold for loading dynamic content (CONFCLOUD-74949) is skipped once the basic frame is loaded for any Figma/Graphy doc, resulting in an incomplete export to PDF.

Steps to Reproduce

1. Create a page with an iFrame;
2. Add as URL any link to a Figma design (you can use this link for example) or Graphy chart;
3. Publish the page and export it to PDF;

Expected Results

The same content displayed within the iFrame in the page is visible in the PDF document

Actual Results

The PDF document has a black box where the Figma design was supposed to be displayed.

Workaround

Currently, there's no workaround within Confluence application to address this issue, but you can still wait for the Figma/Graphy documents to completely load within the page (manually scroll to be very bottom of the page to be sure) and use the Browser's "Print > Save as PDF" feature instead.
