Cocos2D-JS 3.6.1 possible bug: setOpacity / fadeIn shows different behavior on web and iOS

cocos2d-x JavaScript
1

  1. I have some MenuItemImages on my scene and each MenuItemImage has a Sprite and a LabelTTF attached to it as children. MenuItemImages are added to a Menu.

  2. I set the opacity of the MenuItemImages by setOpacity(0).

  3. Then I run fadeIn action on the MenuItemImages.

On iOS: The MenuItemImages and all their children have 0 opacity in the beginning and do the fadeIn action.

On web: Only the MenuItemImages have 0 opacity, the Sprites and LabelTTFs have full opacity. So the Sprites and LabelTTFs are clearly visible from the beginning and only the parent MenuItemImages do the fadeIn action.

I want to know what is causing this irregularity and also the standard way to achieve the iOS behavior on web.

setCascadeOpacityEnabled(true) also had no effect on web.
