Steps to reproduce:

1. Create a new project using Universal 2D project
2. In the Hierarchy, right-click and select 2D Object > Sprites > Square
3. Select the created Square
4. In the Inspector, add "Hinge Joint 2D" Component
5. In the "Hinge Joint 2D" Component, enable "Use Limits" property
6. Click on the button text to "Edit Angular Limits"
7. Click around/drag and observe the gizmo handles in the Scene view
