The Editor freezes when applying changes to a prefab which has child GameObjects with Tilemap components

2D

-

Repro steps:
1. Open user attached project
2. Select game object "Arena" in the Hierarchy
3. Select its child game object "Tilemap"
4. Duplicate it about 5 times
5. Select "Apply" on game object "Arena"

Expected: Changes are applied
Actual: Editor freezes

Reproducible with: 2017.4.5f1, 2018.1.5f1, 2018.2.0b9, 2018.3.0a2

Notes:
- Wasn't able to test with 2017.2 due to project crashing on launch
- Tilemaps added in 2017.2
- If you delete the "Obstacles" game object which has a SpriteRenderer component Unity doesn't freeze no matter how many times you duplicate "Tilemap"
- Crashes in 2018.3.0a2 ( editor.log added )

Fixed in: 2018.3.0a10
