new_data_update is not emitted when the change is a new key in the referenced path

[JapanYoshi]

I am using a reference to listen for changes in a path. However, the signal only fires when an existing path is edited, not when a new key is added somewhere.

Example data at the reference:

listenForMe: {
  items: {
    header: "test"
  }
}

A change that does NOT fire the event:

listenForMe: {
  items: {
    header: "test",
    p_0173: {
      title: "Test title",
      body: "Body text of the test post"
    }
  }
}

A change that DOES fire the event:

listenForMe: {
  items: {
    header: "testtesttest"
  }
}

This is a known fact.
Atm, I don't really know how to deal with that
