WebGL Development builds ignore the "Compression Format" setting when using "Gzip" compression

How to reproduce:
1. Open the “WebGLGZCompressionIssue“ project
2. Make sure to switch the Platform to “WebGL” (File > Build Settings > “WebGL” > “Switch Platform”)
3. Make sure “Compression Format” is set to “Gzip” (Edit > Project Settings > Player > Publishing Settings)
4. Make sure to enable “Development Build”
5. Build the Player
6. Inspect the contents of the “Build” folder

Expected result: Files with the “.gz” extension are present
Actual result: No files with the “.gz” extension are present
