Description Ben Frain 2022-12-08 07:12:14 PST 
Simple operations from the Web Animations API like a composite add do not work as expected in Safari.

This simple example: https://codepen.io/benfrain/pen/JjXQqVO 

Click 'Move Me' to start the box moving, and then click the 'Scale Me' button to add a scale (using composite: add).

It in no way renders as expected in Safari!

Fine in Firefox/Chrome.
