HTML and CSS to reproduce issue
The backface-visibility option does not affect the rendering of the page when printed.
I originally found this issue while trying to print search results from DuckDuckGo that include places:
<a href="https://duckduckgo.com/?q=boston+restaurants&ia=places">https://duckduckgo.com/?q=boston+restaurants&ia=places</a>
Through some subsequent digging, I found that the -webkit-backface-visibility property was no longer hiding content when printing the page. As a result, this causes text that is hidden on screen to appear when printing, and to appear after undergoing the specified transformation (e.g., in the attached example, the 3D rotation causes the text to horizontally be mirrored).
I was able to create a simple HTML page reduction that illustrates this error. No content appears on screen, but when printing, the content of the DIV is visible. Using the HTML file, I confirmed that the issue appears in the current nightly build (Version 9.1.2 (11601.7.7, r204466)).
The attached file provides an HTML file with sufficient CSS to demonstrate the issue.</pre>
