Steps to reproduce:

1. Create a shader graph for UI Toolkit
2. Add the "Texture Size" node
3. Add the "Element Texture Size" node
4. Observe the outputs of the nodes

Actual results: 

Element Texture Size outputs 1x float4

Texture Size outputs 4x float

Expected results: 

The outputs should be the same

Reproducible with versions: 6000.3 6000.4

Can’t test with versions: 6000.2 (no custom shaders)
