Print/Export stops before rendering images in collected pages

[rkwillig]

Describe the bug
When using the Collectives export/print function, the print view opens before all page images are reliably rendered. Text content appears, but one or more images are missing in the print preview and in the printed output.

To Reproduce
Steps to reproduce the behavior:

1. Open a collective that contains pages with images.
2. Click on the export/print action.
3. Wait for the print dialog / print preview to open.
4. See error: no fully loaded images are present in the preview or final print result.

Expected behavior
All page content, including images, should be fully loaded and rendered before printing starts.

Browser log

Insert your browser log here, this could for example include:

a) The javascript console log -> does not show anything suspicious
b) The network log - no 403/404 entries, just 200 and 300 - everything seems to be good.
