Steps to reproduce:

1. Open attached project in an affected version.
2. Open UI document NewUXMLTemplate.uxml.
3. Click on "Label" in Hierarchy.
4. Under Inlined Styles > Text > Outline Width, Letter Spacing, Word Spacing
5. Change the value.

Actual results: Nothing happens.

Expected results: Viewport updates to reflect changes in Inspector.

Reproducible with versions: 6000.1.0b5

Not reproducible with versions: 6000.1.0b4, 6000.0.36f1, 2022.3.57f1

Tested on (OS): MacOS Sequoia 15.2

Notes:

• Did not affect Paragraph Spacing, Color or Shadow.
• You can actually still see it updating in the Editor inspector for the NewuXMLTemplate.uxml.
• Tested both by dragging the value with the mouse, and typing it in with the keyboard and pressing enter.
• Will update if you save, or if you change something else that updates the viewport.
