[WebGL] Incorrect loading progress is shown in the Player when Build files are compressed using Brotli



How to reproduce:
1. Open the attached project
2. In the Publishing Settings, set the Compression Format to "Brotli" (Edit->Project Settings->Player->Publishing Settings)
3. Make a WebGL build
4. Open the built WebGL Player in a browser
5. Spam the refresh button

Expected result: Loading progress is shown iteratively
Actual result: Loading progress is not shown until it reaches 90%

Reproducible with: 2020.2.2f1, 2021.1.0b2, 2021.2.0a2
Couldn't test with: 2018.4.31f1, 2019.4.18f1 (Brotli compressed files don't have the ".br" file extension)

- Web server should be configured to add correct encoding for *.br files
- Player loading progress with Brotli compression jumps from 0 to 90 percent

    Hello, there is no 2021 LTS version. Can you implement this fix into 2020.x LTS? Thank You!

    We would also like to have this fixed in 2020 LTS.
    Or at least provide a way to manually backport the fix

    Will this be fixed in 2020.x as well, seen as that is the current LTS version?
