Issue ID
1195283
Regression
Yes
Scene needs to be saved twice when creating an instance of a Prefab having a Layout Group component and a child UI GameObject
How to reproduce:
1. Open the attached project "1195283.zip"
2. Create an instance of the "test" Prefab in a scene
3. Notice that the scene is marked as dirty
4. Save the scene
Expected result: Scene is no longer marked as dirty
Actual result: Scene is still marked as dirty
Reproducible with: 2018.3.0a11, 2018.3.14f1, 2018.4.13f1, 2019.2.13f1, 2019.3.0b12, 2020.1.0a14
Not reproducible with: 2017.4.35f1, 2018.3.0a10
Notes:
The issue is reproducible with any Layout Group component added to the parent GameObject.
The issue is reproducible with Image, Raw Image or Text component attached to the child GameObject.
The issue does not reproduce when creating an instance of a Prefab created in an unaffected Unity version.

Happens in 2021.3.5f1 and is super annoying with version control, giving twice the amount of work to developers and reviewers when prefabs are included because they have to either remove the changes which are irrelevant or ignore them during the review, but this takes a lot of time.
