Created attachment 462672 [details] Hover fails Hi, Latest Safari TP has caused a regression on transform, which ignore overflow of parent (I think it may be related to the various fixes done on border radius in latest TP). I have been unable to recreate a minimal test case so it seems to be a combinaison of various factors. To reproduce it, open this page: https://impact-theme-sound.myshopify.com/pages/paris-saint-germain (if you see a password use rewblo to enter into the store). Then scroll to the "Master & Dynamics X Paris Saint Germain" at the end of the page, and hover the block (see attached screenshot). Despite the image being in a overflow: hidden container, during the complete animation it is visible outside the parent bounds.
I can reproduce with STP 154. Testing notice: logging in sends you back to the landing page, so you need to go to https://impact-theme-sound.myshopify.com/pages/paris-saint-germain again.
