Shader Graph Swizzle Node Input/Output and Mask Update Incorrectly After Undo
Steps to reproduce:
- Open a new shader graph
- grab some node (like world position) that can output a vector
- place to swizzle nodes on the graph
- use the vector node as input for the first swizzle, and the output of the first swizzle as input for the second.
- Ensure the second node is set to have a mask of 'xyzw'
- Ensure the first node is set to have a mask of 'xy'
- This should produce an error on the second node stating a mismatch in number of vector components.
- Now change the mask of the first node from 'xy' to 'xx'
- hit ctrl/cmd+z to undo this change
- click on the input field for the mask of either swizzle node
- click off
- Notice the nodes updating erroneously.
Actual results: The nodes appear to have some underlying data updated that 'resolves' the vector component disparity, but has potentially erroneous and regressive behavior for the shader.
Expected results: The second swizzle node remains correctly in an error state due to mismatching vector component count.
Reproducible with versions: 6000.0.58f1, 6000.1.0f1, 6000.4.0a2
Tested on (OS): MacOSX Tahoe (MacEditor ARM M1 Max)
