Repro steps:
1. Create a new shadergraph
2. Create two new vector1 properties
3. Reorder the two properties
4. Select the first property, then the second property, then the first again, then the second
5. Reorder the two properties again
6. Undo so that the second reorder is undone
7. Press undo until the first reorder is undone
Expected result: it undoes the first reorder immediately, or selects the properties the way you did in between reordering
Actual result: it does 4 undo steps that appear to do nothing

Note: this complicates one of the testrail cases for shadergraph, making it ambiguous as to whether to mark it as passing or not, since there are extra undo operations that must be performed to complete the testrail case
