Exporting PDF doesn't include iframe screenshot

[rokkondic]

Describe the Bug

Exporting a page as PDF leaves the iframe part blank. We have a map of our facility inserted as an iframe on a page, which is exported periodically as a PDF via API. The text, tables and images are exported fine, but the iframes are left blank.

Steps to Reproduce

1. Go to any page that includes an iframe
2. Click export to .pdf
3. The page is blank where the iframe should be

Expected Behaviour

The PDF should be exported with the iframe as a screenshot, similar to how ti is shown if you print the page (Ctrl + P) in the browser.
