Reproduction steps:
1. Create a new Unity project
2. Check the "Name Files As Hashes" box in the Player Settings > Settings for WebGL > Publishing Settings
3. Build a Development Build player on the WebGL platform
4. Go to the build folder and observe the names of the files

Expected result: The MD5 hash of the uncompressed file contents is used as a filename for each file in the build
Actual result: The MD5 hash of the uncompressed file contents isn't used, and files are named after the build name

Reproducible with: 2019.4.37f1, 2020.3.32f1, 2021.2.18f1, 2022.1.0b13, 2022.2.0a9
