Memory Profiler reports wrong Mesh size results when generating it with JOBS

Profiling

-

How to reproduce:
1. Open the user's attached "MeshMemoryUsage" project
2. Open the "SampleScene" Scene
3. Enter the Play Mode
4. Select the "Generate Mesh" button in the Game View
5. Compare the "_expectedTotalSize" and "resultingSize" values

Expected result: The "_expectedTotalSize" value calculated in the user's script matches the Memory Profiler "resultingSize" reported value
Actual result: The values differ ~200 times

Reproducible with: 2020.3.19f1, 2021.1.28f1, 2021.2.1f1, 2022.1.0a14
Couldn't test with: 2019.4.32f1 (user script error related with method nonexistence in earlier versions)

Note: Disabling the "GameObject -> Mesh Oddness Repro (Component) -> Use Dots" boolean value generates Mesh in other method, where the "_resultingSize" value is almost twice higher than "_expectedTotalSize"
