Rotated elements animate, but only linear easing is applied even if any other type of easing is specified. Prior to 13.1, I beieve behaviour used to be manageable by including the web-animations.js polyfill, but now this is not the case. https://codepen.io/createwithflow/pen/JjGjWGq May be similar to: https://bugs.webkit.org/show_bug.cgi?id=203476 However, the issue above is not dealing with CSSTransition.

Thanks for filing this bug Travis. This is already fixed and you can see the correct behavior in Safari Technology Preview. This is most likely a duplicate of bug 210526. *** This bug has been marked as a duplicate of bug 210526 ***

Ah, great and apologies for the dupe. I even had a copy of the tech preview, I'll be more careful to review the list of open / closed bugs. This was my first ticket. T

No need to apologize, it's a lot more valuable to file a potential duplicate than not to file a bug assuming it might be.
