Steps to reproduce

1. Go to code sandbox
2. Click on append
3. See the isDirty state of the first item in the array turns to true when it supposed to be false. (because no changes have been made to the first item)

Expected behaviour

when I append a new item in the array, should only the new item and the array to have their dirty states to be true? Why would the previous items dirty states is set to true too?

What browsers are you seeing the problem on?

Firefox, Chrome, Safari, Edge
