How to reproduce:
1. Open the “BuildTest.zip“ project
2. Enter Play Mode (or Build and run with Development Mode and Autoconnect Profiler)
3. Press T to load another scene asynchronously with LoadSceneMode.Single (and then press Y to unload unused assets)
4. Observe the Console

Expected result: Nothing is logged (every object is destroyed and not saved)
Actual result: “Alive gameObject: no_parent_flag_set_editor“ and “Alive gameObject: no_parent_flag_set_editor_build“ info logs are being logged

Reproducible in: 2023.1.0a1, 6000.0.56f1, 6000.2.2f1, 6000.3.0a6

Reproduced on: Windows 11 Pro (24H2)
Not reproduced on: No other environment tested

Notes:
- Only reproducible under these circumstances:
1. The object does not have a parent
2. The object has a HideFlags.DontSaveInEditor flag
3. Scene is loaded with LoadSceneMode.Single
- Either the documentation is incorrect, or the flags don’t work correctly
