Steps to reproduce:

1. Create a new project using Universal 3D template
2. In the Project window, right-click -> Create -> Shader Graph -> URP -> Lit Shader Graph
3.  Open the Shader Graph, right-click -> Create Node ->Matrix 2x2
4. Observe the Node
5. In any of the value field, enter a really number so that "Infinity" text appears
6. Observe the Node

Actual results: Value cells are misaligned with larger right padding, and the “Infinity” text is clipped and never fully visible

Expected results: Value cells are evenly centered with balanced padding, and the “Infinity” text is fully visible

Reproducible with versions: 6000.4.0b11, 6000.5.0a8

Not reproducible with versions: 6000.3.10f1, 6000.4.0b10

Tested on (OS): Ubuntu 24.04, macOS 26.2

Notes:

• Regression is primarily in the default layout (uneven right padding). Prior to the UUM-134329 fix, entering large values would stretch the node indefinitely; after that fix, the fields no longer stretch but the layout remains misaligned and the “Infinity” label is clipped
