Bug: Undo causes resized reroute nodes to go back to original sizing

1. Create 2 reroute nodes
2. Resize the 1st node to some arbitrary size, then do the same for the 2nd
3. Hit Ctrl+z, watch all nodes return to original size instead of just the 2nd one

I don't think this issue is relegated to just undoing after a node resize, but undoing after any operations reverts all nodes to original sizing.

EDIT: After experiencing more issues, I think the undo feature is just broken. After moving/resizing some nodes, I hit Ctrl+z and for some reason I was brought back into one of the clip text prompt boxes and my text was undone.
