*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

*Notes:*
* Reproduces whether the window is docked or not, and if fullscreen or not
