Grouped shapes not rendering #2239

I think this might be a bug on iOS/macOS engine where if you group shapes in a layer they won't render

Lottie 4.0.1

Behavior where shapes are not grouped and do not have transform animations: https://www.dropbox.com/scl/fi/5mqfsevi3ic5k66alauvk/Lottie-iOS-Shapes-Working.mov?rlkey=y2i5b4q78mthk9gpg6ra4qjy3&dl=0

On each behavior video I included the Web Player 1.5.7 that works in both cases

Animation JSON: grinn11.json

Update: When using the Main Thread rendering engine with Lottie 4.3.3, the shapes render just fine so the problem is with the Core Animation rendering engine.

issue is still there for 4.3.4 but switching to main thread engine works correctly
