Editor crashes when adding a script with a UI component requirement to a parent Gameobject



How to reproduce:
1. Open the scene "NewScene" from my attached project "New Unity"
2. Select "Parent" GameObject and from the Assets folder drag a script called "Test2" to its Inspector window

Expected result: There should be a Text component created for the "Parent" GameObject automatically
Actual result: Editor crashes

Reproducible with: 2017.2.2p4, 2017.4.3f1, 2018.1.2f1, 2018.2.0b5

Note: Last stack trace output (Transform::SetParent). Crash doesn't occur with these UI class components: Button, DefaultControls, InputField, Navigation, Selectable. The crash occurs when a script with "[RequireComponent()]" attribute is being added to the parent object in Hierarchy
