Animation Search bar’s “x” delete button disappears when a Search Area was added and “Enable” was toggled

Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Open the Animation window (Window > Animation > Animation)
3. Dock the Animation window
4. Create a new Cube GameObject in the Hierarchy
5. Select the newly created Cube GameObject in the Hierarchy
6. Create a new Animation in the Animation window
7. Click the "Add Property" button
8. Right-click the Transform properties and select "Add Properties"
9. Click the lens button in the Search bar
10. Select "Components"
11. Select "Transform"
12. Right-click Transform in the Search bar and select "Enable"
13. Repeat step 12
14. Observe the Search bar

Actual results: There is no "x" delete button

Expected results: There is "x" delete button
