How to reproduce:
1. Create a new project using the default 3D template
2. Import the Addressables package
3. Open the package's "AsyncOperationHandle.cs" script
4. Inspect the "WaitForCompletion" method
5. Check the value passed into ResourceManager.Update

Expected result: The expected parameter and actual passed parameter is the same
Actual result: Time.deltaTime is passed when the expected parameter is Time.unscaledDeltaTime

Reproducible with: 1.18.13 (2019.4.29f1, 2020.3.16f1, 2021.1.17f1, 2021.2.0b5, 2022.1.0a4)

Note:
- It's not limited to WaitForCompletion, other ResourceManager.Update usages show the same Time.deltaTime value passed as well
