AssetBundle, WebGL and Activation-Tracks

Hi.

I'm currently investigating a problem with our WebGL-App and AssetBundles.

Simple Setup to reproduce:
The AssetBundle has a timeline with an Activation-Track which activates and deactivates a cube and an Animation-Track which starts an animation on another cube.


In Editor, Playmode, AssetBundle loaded into App in Editor everything works fine, even when I build this Asset as a standalone WebGL-Player.

But if I load the AssetBundle into the App build with WebGL and open it with Firefox for example the Activation-Truck does nothing but the Animation-Tracks plays perfectly fine.

Someone has any idea what is going on?

Tested this in Unity 2018.2.20f1 and Unity 2018.3.2f1

 

Fixed it... Seems it got stripped away although Strip Engine Code was disabled in Player Settings. Putting a Timeline with all Tracks inside the main-scene of the app and build it again did the trick.
