[AssetBundle] "The referenced script (Unknown) on this Behaviour is missing!" errors when loading object from Asset Bundle

Asset Bundles

Aug 22, 2019

How to reproduce:
1. Open the "BundleTest.zip" project
2. Open the "Scene1.unity" scene
3. Build Asset Bundle
- Test -> BuildBundle, You can see the assetbundle in BundleTest/bin folder
4. Edit Game.cs script
- change the Asset Bundle file path in AssetBundle.LoadFromFile("your project folder/bin/bundletest");
5. Enter Play mode

Actual result: 3 warnings are thrown into the console about missing references.
Expected result: No warnings are thrown.

Reproducible with: 2020.1.0a1, 2019.3.0b1, 2019.2.3f1, 2018.4.7f1.

Notes:
- The issue is not reproducible if line "var ao = EditorSceneManager.LoadSceneAsyncInPlayMode (SCENE2, new LoadSceneParameters (LoadSceneMode.Single));" Game.cs: 23 is commented out.
- Can't test 2017.4 as EditorSceneManager.LoadSceneAsyncInPlayMode is not implemented there.

-----------------------------------
Fixed in 2020.1.0a9, 2019.3.0b10, 2019.2.13f1, 2018.4.13f1.
