Regression
Yes
Turning off a child object in Canvas, applying changes to prefab, then turning on again breaks it's layout
This is happening only when an object with TextMeshPro components are used in the Canvas.
Steps to reproduce:
1. Open QA's attached project
2. Open scene "Main"
3. Select "Background" under Canvas\ComplexPrefab in the Hierarchy
4. Disable it and apply changes to prefab
5. Enable "Background"
Expected result: Layout stays unchanged
Actual result: Layout completely messes up
Reproduced with: 2017.3.0b5, 2017.3.0f3, 2018.0a7
Not reproduced with: 5.6.4p4, 2017.1.2p4, 2017.2.1f1, 2017.3.0b4
Regression introduced in 2017.3.0b5

Encountering this issue even when *not* using TextMeshPro components - Layout for deactivated objects are broken when prefabs are applied.
