*Description:* When styling UI within the Inspector in UI Builder and changing a property with multiple child properties (e.g. Border Width), the USS generated defines the value of each child property instead of using the shorthand that affects all the child properties automatically.

*Steps to reproduce:*
# Open a URP Unity project
# Open the UI Builder via Window > UI Toolkit > UI Builder
# Ensure the UXML Preview pane at the bottom is visible by expanding it
# Create a Visual Element by dragging it from the Library to the Hierarchy
# Make sure the Visual Element is selected and its details are visible in the Inspector
# Find the Width option under Inlined Styles > Border
# Change Width to 2px

*Actual results:* In the UXML preview, the generated USS has added all four width edges separately with their values set to 2px instead of doing the shorthand and much more readable 'border-radius: 2px;'
