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. 1659512 1 graouts 2020-06-05 01:31:11 -0700 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 *** 1659514 2 travis 2020-06-05 01:37:08 -0700 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.
