GameObject not disbled when changing the sibling order inside OnDisable

1. What happened
If we change the sibiling order of an object inside OnDisable, it can cause that some objects aren't disabled during DestroyObject.
This leads to a lot of undefined behaviours.

This is due to how we iterate the objects in [Internal link]

2. How we can reproduce it using the example you attached

• Open SampleScene
• Enter play mode

Expected behaviour:

• Both objects log from OnDisable

Actual Behaviour:

• Only Child1 logs from OnDisable
• The editor might crash due to trying to destroy an enabled GameObject
