Undoing actions results in incorrect values instead of returning values from previous state

How to reproduce:

1. Create a new particle system
2. Add a set position block in initialize
3. Drag-change the value
4. Press Ctrl+Z/CMD+Z to undo an action

Expected result: Value is restored to 0

Actual result: Value is 0.03

Notes:

• This also affect other blocks and fields

• When continuously undoing actions error is thrown - System.Exception: Unable to retrieve current state at : 14 (max 24) at UnityEditor.VFX.UI.VFXGraphUndoStack.RestoreCurrentGraphState
• Undo History is also affected
