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 Button (GameObject > In-App Purchasing > IAP Button)
4. Open the IAP Catalog in the Inspector window
5. Observe the "ID" Text Field and the "Type" dropdown
6. Resize the IAP Catalog window smaller and bigger
7. Repeat step 5

Actual results: The "ID" Text Field and the "Type" dropdown does not scale properly with the window, there is space for both to be longer/bigger but that space is unused and the text in the "Type" dropdown gets cut off even if there is space for it. This is even worse if the window is docked

Expected results: The "ID" Text Field and the "Type" dropdown scales properly with the window, like the "Locale" dropdown for example

Reproducible with versions: 6000.0.60f1, 6000.2.8f1, 6000.3.0b7, 6000.4.0a3

Tested on (OS): MacOS Silicon Sequoia 15.6.1

Notes:

• The dropdowns, textfields etc. should be consistent throughout the window and use the needed space when available
