When GreenSock write matrix3d on CSS Transform based on force3D / Perspective / TransformOrigin the clip-path css attribute animation just break in the Latest Safari (12.1 (14607.1.40.1.4)).
See our Example above in SAFARI Latest Version, or on any iOS latest version !! .
Click on Working and Not Working version to see the Effect. The only Different between those functions are the "force3d:true" setting !
Hope you have a good idea for this ?
