Dynamically loading Timeline from AssetBundle causes "Assertion failed on expression: 'pred(*previous, *i)"

Asset Bundles


Steps to reproduce:
1. Open user attached project
2. Play the scene
3. Observe the "Assertion failed on expression: 'pred(*previous, *i)'" in the console (if the error does not occur, relaunch the editor)

Expected result: "Assertion failed on expression: 'pred(*previous, *i)" should not appear when Timeline is loaded from an AssetBundle
