How to reproduce:
1. Create a new Unity project and install the Cinemachine package
2. In the Hierarchy, right-click -> Cinemachine -> Cinemachine Camera
3. In the Inspector, navigate to the "Tracking Target" under the "Cinemachine Camera" Component
4. Press the "Gear" button -> "Use Separate LookAt Target"
5. Try pressing on any of the "Gear" buttons

Expected results: The buttons are responsive each time
Actual results: The buttons are unresponsive most of the times

Reproducible with: 3.1.3 (6000.2.0b2)
Can't test with: 2.10.3 (6000.2.0b2) (Different functionality)

Reproducible on: macOS Sequoia 15.4 (M1)
Not reproducible on: Windows 11

Note: The button usually works unless you click "Use Separate LookAt Target", after that, both "gear" buttons barely work, and if it is converted back, the button remains broken
