View.setAlpha causes unexpected rendering

[jbr-sleepwave]

Describe the bug
Applying alpha on the LottieAnimationView is "broken".

What version of Lottie did you test this on?
6.6.2, 6.3.0 - broken
3.4.0 - works

What version of Android did you test this on?
A10, 13, 14, 15

Steps To Reproduce
Have lottie animation with multiple layers.
For example this one
https://lottiefiles.com/free-animation/halloween-pumpkin-black-cat-i28jx8Xt3X
lottie_animation.zip

Start changing alpha of the LottieAnimationView in animation or simply via View.setAlpha
(lottie paused at the time of changing alpha)

• lottie_renderMode from xml any value doesn't seem to have any effect

Video:
animation is changing alpha to 0 in 2s to have "fade out" effect.
Looks like the alpha is set to each layer individually ? it doesn't fade out consistently as expected.
