Created attachment 474461 [details] HTML that, when exported as PDF, will include flipped text Steps to repro: 1. Open the attached HTML in Safari Technology Preview (or in Safari in macOS 15.4b2) 2. Choose File > Export as PDF… 3. In the exported PDF, the "Lorem ipsum" text will be flipped. This appears to be due to the two `transform` CSS properties in the HTML. If there is only one, the bug does not appear. The actual value for the `translateX()` doesn't appear to matter: the text is flipped regardless of the value.

Hello, thank you for the report! Which version of Safari Technology Preview are you seeing this on?

I've only tested it on the Safari Technology Preview (Release 214). Though it also appears in macOS 15.4 beta 2.

This appears to be caused by https://commits.webkit.org/288504@main (enablement of Remote Snapshotting).

This is broken in macOS 15.5 Beta (24F5042g) and Safari Technology Preview (215). Reopening.

It looks like the above commit hasn't yet pulled into Safari Technology Preview 215, so the fix never made it there. However, the bug was fixed in Safari 18.4 but is once again broken in Safari Version 18.5 (20621.2.1.11.5)
