Cocos creator 3.x, change spine opacity on Android doesn't work

Creator 3.x
#1

I try to change opacity of skeleton using cc.UIOpacity and alpha in color property of sp.Skeleton component. It works on web, but the Android doesn’t work. I tried on Cocos Creator 3.4.2 and 3.5.0.

#2

This is a known issue that is expected to be fixed in 3.6.
If you really need to fix this issue, you can try this modification, but it will increase jsb calls.
