Can't undo first item in history

[SergeBerwert]

Since the update to undo 1.3.0+1 I cannot undo the first element in the history. The status of the property canUndo is false although the history list still contains an element.

As you can see in the screenshot of the watch _history has one element but canUndo is false and calling the function undo dose not work. it works as expectet in version 1.1.0+1

I have the same issue, atm you can try my pull request #6 until @rodydavis can approve it

dependency_overrides:
  undo:
    git:
      url: git://github.com/ductranit/undo.git

I can make it an option, most times initial state you want to protect. But I can add a parameter 👍🏼

Fixed with version 1.3.1
