Parent class Awake method is not called when Reload Scene setting is disabled and child class has [ExecuteInEditMode] attribute

Scripting

-

How to reproduce:
1. Open the user-submitted project
2. Open the Sample Scene
3. Enter Play mode

Expected results: "Awake was called: True" is printed
Actual results: "Awake was called: False" is printed

Reproducible with: 2019.3.0b9, 2019.3.0f4, 2020.1.0a11, 2020.1.0a18

Not reproducible with: 2019.3.0b8, 2020.1.0a9

Notes:
The issue is not reproducible on Unity 2019.2 and below, because Enter Play Mode Settings functionality is not available.

  1. Resolution Note (2020.1.X):

    This is an intentional change and by design.

    See "Important differences due to skipping Scene Reload" in this thread: https://forum.unity.com/threads/configurable-enter-play-mode.768689/

    "ExecuteInEditMode/ExecuteAlways scripts are not destroyed/awaken - no OnDestroy/Awake calls for those.
    Watch out for Awake/OnEnable methods which check EditorApplication.isPlaying property - Awake is not called and OnEnable is called only when EditorApplication.isPlaying is already true on Play Mode change."

    The issue has been fixed in Unity 2020.1.0a23 and above
