transition.data not kept across transition retry

[Techn1x]

Hi! I'm trying to make use of transition.data to keep a count of transition retries. Something like the following;

// application route
@action
error(error, transition) {
  if (error.retryable) {
    const transitionData = transition.data || {}
    const { retryCount = 0 } = transitionData

    if (retryCount < 3) {
      transition.data = { ...transitionData, retryCount: retryCount + 1 }
      transition.retry()
    } else {
      // some other remedy
    }
  }
}

Unfortunately, it seems what I set in transition.data is forgotten when the transition is retried - if that retried transition fails and re-enters the error hook, retryCount is gone. The Ember docs specifically mention that this should work https://api.emberjs.com/ember/3.27/classes/Transition/properties/data?anchor=data

Properties set on data will be copied to new transitions generated by calling retry on this transition

---

As a workaround, I have found that I can set transition.intent.data and it remembers it across the retry. Though I am not sure of the implications of doing that (if any)

It might be related to #77 though that issue seems very old!
