Steps to reproduce:

1. Create a new Unity project using the Universal 3D template
2. Install the In-App Purchasing package
3. Create a new IAP Listener (GameObject > In-App Purchasing > IAP Button)
4. Resize the Inspector window horizontally to be smaller
5. Observe the Inspector window

Actual results: IAP Listener lists titles go out of their bounds (grey background)

Expected results: IAP Listener lists titles are confined within their bounds

Reproducible with versions: 6000.0.60f1, 6000.2.9f1, 6000.3.0b7, 6000.4.0a3

Tested on (OS): Ubuntu 24.04, MacOS Silicon Sequoia 15.6.1

Notes:

• Does not reproduce with IAP Button even though it has exactly the same lists
