Steps to reproduce:
1. Create a project which has Editor script from http://docs.unity3d.com/Documentation/ScriptReference/EditorGUI.LabelField.html
2. Click on menu "Examples" -> "Foldout Usage"
3. Select any gameObject, foldout example should show its name.
4. Clicking on name will not fold-out the Foldout, but clicking on arrow next to the name will. This behavior is not consistent with the way foldouts in Inspector work - clicking anywhere in the horizontal area of a foldout's arrow toggles the component to fold out.
