[WebGL] Async Tasks do not run on WebGL when Threading is enabled
Reproduction steps:
1. Open the attached project ("case_1243010-WebG-Threads.zip")
2. Open the repro scene ("SampleScene")
3. Enter Play Mode
4. Notice the logs about async tasks being printed out to the screen
5. Exit Play Mode and make a WebGL build
6. Run the build and inspect the printed messages on the screen
Expected result: Async task messages are printed to the screen
Actual result: Only 'Start' and 'End' messages are printed to the screen (async tasks doesn't run)
Reproducible with: 2019.3.14f1, 2020.1.0b9, 2020.2.0a11
Couldn't test with 2018.4 (errors when building the project)
Tested with: Chrome (81.0.4044.138)

Just tested in 2019.4.7f1, it does not work.
Simple thing like this does not work:Test.text = "1";
await Task.Delay(1000);
Test.text += "2";
await Task.Delay(1000);
Test.text += "3";Unity only pretends it's multi-platform, it's actually multi-pain.
