[WebGL] "wasm streaming compile failed" browser errors occur when launching any Unity project on a server
How to reproduce:
1. Create a new Unity project
2. Build it for the WebGL platform
3. Launch the project on a localhost server (XAMPP was used in this case)
4. Inspect the browser page and navigate to its console
Expected result: browser console errors do not occur
Actual result: an empty Unity project causes a MIME type related error
Reproducible with: 2020.1.0a7, 2020.1.0b4, 2020.2.0a5
Not reproducible with: 2017.4.39f1, 2018.4.20f1, 2019.3.8f1, 2020.1.0a1, 2020.1.0a6
Notes:
1. Full errors:
1.1: wasm streaming compile failed: TypeError: Failed to execute 'compile' on 'WebAssembly': Incorrect response MIME type. Expected 'application/wasm'.
printErr @ 5.loader.js:31
1.2: falling back to ArrayBuffer instantiation
printErr @ 5.loader.js:31
2. If the WebGL build does not load in the browser, build with "Development Build" ticked in the Build Settings

We're also seeing this on 2020.2.6, without "name files as hashes"

This is not a duplicate of issue #1223772: It also happens without name files as Hashes option.

Hi there— I see that this is "resolved" on the duplicate issue, fixed for 2020.2.x, but I am using 2020.3.0f1 and I am experiencing the same exact issue. Could I be formatting something differently to avoid this error?
