[WebGL] Some AudioClips cannot be decompressed on builds when loaded from Asset Bundle

WebGL

-

How to reproduce:
1. Open the attached project ("case_1180101-TestBgmAssetBundle.zip")
2. Open the repro scene ("SampleScene")
3. Switch platform to WebGL
4. Build asset bundles (TestBgAssetBundle > BuildAssetBundle)
5. Build and run the project
6. Click "Load B" buttons

Expected results: Audio file is decompressed from the asset bundle
Actual results: Error is thrown when trying to decompressing the audio file from the asset bundle

Reproducible with: 2018.4.8f1, 2019.2.4f1, 2019.3.0b2, 2020.1.0a3
Couldn't test with 2017.4 because missing "UnityWebRequestAssetBundle'" method

Note:
This issue does not reproduce when the audio file is loaded directly from the build (not stored in the Asset Bundle)

  1. Resolution Note (fix version 2020.1):

    Not reproducible with Unity 2018.4.28f1, 2019.4.13f1, 2020.1.10f1, 2020.2.0b8, 2021.1.0a2
