Editor crashes when adding text component to game object in play mode via the script

UI

-

-

Priority: 2Necessary for shipping a final release

-

Severity: 1Crash or major loss of functionality

How to reproduce:
1. Open the attached project
2. Open and play ExampleScene
Result: Editor freezes and crashes after some time

Note: crash log is not generated. If one comments this part uiText = uiTextGameObject.AddComponent<Text>(); from DrawableLabel.cs line 96 project doesn't crash. it somehow forces the OnDisabled Unity message fire up for the AFPSCounter.cs MonoBehaviour. It leads to the infinite cycle of the OnDisable \ OnEnable messages

    Yeah but this workaround will not work in an Awake call because of this bug :
    https://issuetracker.unity3d.com/issues/error-when-creating-a-recttransform-component-in-an-awake-call-of-an-instantiated-monobehaviour
    The change you mentioned seems to cause a lot of UI related problems, how did it make it to so many branches ?

    We have made some changes that require us to disable and then reenable the entire transform hierarchy whenever we replace a Transform with a RectTransform. This has created the undesirable side effect of calling OnDisable/OnEnable on all scripts attached to the hierarchy. This is a behaviour that we intend to address in the future.

    There is a simple workaround for this though. The problem is caused by when we swap the transform, so a simple solution is to add a RectTransform or UI element to the GameObject on creation so that the swap does not need to be performed.

    For example
    var go = new GameObject("Canvas", typeof(RectTransform));
