node icon doesn't update properly after undoing an edit

[rickmastfan67]

Steps to reproduce:

1. Load the attached file.
2. Select the draw tool (a) and draw a line from the middle node on the small way in the attached file. (doesn't matter what direction)
3. Now, hit the 'undo' button (or Ctrl+Z) to undo drawing that new way.

What happens:
The middle node of the original way in the file still indicated there's an intersection of ways there.

What should happen:
The middle node of the original way should return to being displayed as a 'normal' node along the way and not indicate there's an intersection there that doesn't exist.

NOTE: If I were to delete the way that was drawn from the middle node instead of undoing the edit, the middle node does properly update.
