Steps to reproduce:

1. Create a new Unity project using the Universal 2D template
2. Create a new Triangle Sprite (Assets > Create > 2D > Sprites > Triangle)
3. Select the newly created Triangle Sprite
4. Click the "Open Sprite Editor" button in the Inspector window
5. Change the Sprite "Name" property to something that's very long in the Sprite Editor window
6. Click the "Apply" button in the Sprite Editor window
7. Expand the Triangle asset by pressing an arrow on the right of its icon in the Project window
8. Select the renamed Sprite in the Project window
9. Observe the Inspector window

Actual results: Sprite name labels are overflowing and are not truncated both in the Inspector window and the Preview section

Expected results: Sprite name labels are truncated
