AssetBundle bytes differ between builds when identical content is rebuilt in a new Editor session

How to reproduce:

1. Extract the attached project “IN-152848”
2. Ensure that the Library folder is not present in the project’s directory
3. Build AssetBundles in batch mode using “-executeMethod ABBuild.Run”
4. Delete the generated Library folder in the project’s directory
5. Repeat step 3
6. Observe the AssetBundle hashes

Actual result: One or more AssetBundles differ byte-for-byte even though no content changed
Expected result: AssetBundle bytes are identical across builds from identical source content

Reproducible with: 6000.0.53f1, 6000.0.58f2
