Animation window text overflows and clips container bounds

Steps to reproduce:

1. Create a new project
2. Add any game object in the "Hierarchy" window
3. Rename it (make its title longer)
4. Select the renamed game object
5. Go to "Window -> Animation -> Animation"
6. Observe how the string "To begin animating ..." is displayed in the window
7. Dock the window next to the "Game" window or "Inspector" window
8. Observe how the string "To begin animating ..." is displayed in the window

Actual results: As shown in Padding Issue.png, the text extends horizontally with zero bounding margin padding

Expected results: The text should wrap automatically and stay contained within the panel, using standard side padding to prevent clipping or overlapping with window dividers

Reproducible with versions:  6000.6.0a7

Tested on (OS): macOS - Tahoe 26.5
