Steps to reproduce:
1. Create new Unity project using Universal 3D Template
2. In Hierarchy window create an Empty GameObject
3. Open Animation window (Window > Animation > Animation)
4. In Animation window press “Create” to create Animation Clip
5. Dock the Animation window beside the Console (bottom row) and shrink it until the Dopesheet/timeline pane on the right is no longer visible, only the property list (GameObject : Position) or property value fields remain
6. Add Transform Position value
7. Try changing Position.x value to 1
8. Observe the value field
Actual results: the Position.x value field does not accept any input, typing value and pressing Enter has no effect, editing property values is not possible while the Dopesheet is hidden
Expected results: the Position.x value field accepts the input, entering value sets the value and creates/updates a keyframe at the current frame
