Repro steps:
1. Open shadergraph
2. create a "Position" node
3. create a "Remap" node
4. plug the output of "Position" into "In" of "Remap
Expected result: the output of Remap turns yellow to reflect the new output type, and the label turns to Out(3)
Actual result: the output stays blue and stays as Out(1), and if plugged into a node will look as if it's being recast from a vector1 to a vector3, although the end result in the preview and resulting shader will be correct.
