1710822 - Image not visible when printing from iframe with srcdoc

Status: RESOLVED FIXED

(Core :: Printing: Output, defect)

Description

Attachment: firefox.jpg

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:88.0) Gecko/20100101 Firefox/88.0

Steps to reproduce:

I create an iframe with a srcdoc set as single image element. The img element's src is set to a path that doesn't have the domain name. So something like <iframe srcdoc="<img src=&quot;/image.png&quot;>">. I then get a reference to the iframe and try to print its contents with myiframe.contentWindow.print().

Actual results:

In the browser, the image is visible within the iframe. In the print-preview, the image is not shown. The print process completes successfully. However, the result (using "Save to PDF ") appears to be missing the image.

Expected results:

The print-preview and resulting pdf should contain the image referenced in the iframe.
This works with my versions of chromium-browser, microsoft-edge & opera.

The Bugbug bot thinks this bug should belong to the 'Core::Printing: Output' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

So that we correctly avoid choosing about:srcdoc as a base URI.

Ah, my patch fixed the image when printing the top-level page, not when printing the iframe itself via window.print(). Let's fix that in a separate bug, so that tracking it isn't confusing.
