Decompressing a DeflateStream under IL2CPP misses a few bytes

Reproduction steps:
1. Open the attached “Repro” project
2. Open the “Assets/Scenes/SampleScene.unity” Scene
3. Build And Run the project (File > Build And Run)
4. Observe the test results in the top-left corner of the Player

Expected result: Both test results are true
Actual result: Deflate test result is false

Reproducible with: 2021.3.30f1, 2022.3.10f1, 2023.1.15f1, 2023.2.0b11, 2023.3.0a7

Reproducible on: Windows 10 Pro (22H2)
