Align section button groups are partially cut off in UI Builder when Inspector is at default width

Steps to reproduce:

1. Create a project.
2. In the Project window > right click > Create > UI Toolkit > UI Document.
3. Open the newly created asset in the UI Builder window.
4. Add any element to the UI Builder Hierarchy.
5. In the UI Builder Inspector, scroll down to Inlined Styles > Align.
6. Observe all the button groups in this section.

Actual results: All button groups are fully visible.

Expected results: All button groups are partially cut off at the end.

Reproducible with versions: 6000.0.18f1, 6000.0.13f1

Not reproducible with versions: 6000.0.12f1, 2022.3.44f1, 2021.3.43f1

Tested on (OS): Ubuntu 24.04, MacOS Sonoma 14.6.1

Notes:

• Ran into this while looking [Internal link] and incorrectly following its repro steps into the wrong section.
• Recording shows how Ubuntu opens windows at an unusable minimum size ([Internal link]), but this also happens on MacOS which isn't affected by this issue.
