Search bar flickers with “animation:” when the “Animation (animation:)” Search Area is clicked in the Animation window

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. Select any GameObject in the Hierarchy
5. Create a new Animation in the Animation window
6. Click the lens button in the Search bar
7. Select the Animation Search Area
8. Observe the Search bar

Actual results: “animation:” appears and disappears instantly

Expected results: “animation:” does not appear or stays in the search bar (not flicker)

Reproducible with versions: 6000.6.0a7

Can’t test with versions: 6000.0.77f1, 6000.3.18f1, 6000.4.12f1, 6000.5.1f1, 6000.6.0a6 (due to no Search bar)
