Steps to reproduce:

Create a new Unity project using the Universal 3D template
Create a new "Cube" GameObject (GameObject > 3d Object > Cube)
Open the Animation window (Window > Animation > Animation)
Create a new animation by pressing the "Create" button in the Animation window
Open the Animator window (Window > Animation > Animator)
Click "Layers" button in the Animator window
Create a new layer with a very long name
Observe the Animator window

Actual results: The "Auto Live Link" button disappears because the layer name is too long

Expected results: The layer name either has a limit of characters or is truncated in the Animator window

Reproducible with versions: 2021.3.51f1, 2022.3.64f1, 6000.0.52f1, 6000.1.9f1, 6000.2.0b8, 6000.3.0a1

Tested on (OS): macOS Silicon Sequoia 15.5
