There are 3 markers showing up for the loading phase of the HTML page:

1. The initial load.
{
  "start": 512335.72875789064,
  "dur": 3056.424849999952,
  "name": "Load 36: https://www.mozilla.org/",
  "title": null,
  "data": {
    "type": "Network",
    "startTime": 512335.72875789064,
    "endTime": 512337.07070589066,
    "id": 56264071577636,
    "status": "STATUS_START",
    "pri": 0,
    "URI": "https://www.mozilla.org/"
  },
  "incomplete": true
}

2. The answer with the redirection
{
  "start": 505780.25126389065,
  "dur": 6618.132344999933,
  "name": "Load 1884: https://www.mozilla.org/",
  "title": null,
  "data": {
    "type": "Network",
    "startTime": 505780.25126389065,
    "endTime": 512398.3836088906,
    "id": 13589276526428,
    "status": "STATUS_REDIRECT",
    "pri": -20,
    "URI": "https://www.mozilla.org/",
    "RedirectURI": "https://www.mozilla.org/en-US/",
    "fetchStart": 512337.07070589066
  },
  "incomplete": true
}

3. The final answer.
{
  "start": 505780.25126389065,
  "dur": 6700.485168999992,
  "name": "Load 1884: https://www.mozilla.org/en-US/",
  "title": null,
  "data": {
    "type": "Network",
    "startTime": 505780.25126389065,
    "endTime": 512480.73643289064,
    "id": 13589276526428,
    "status": "STATUS_STOP",
    "pri": -20,
    "URI": "https://www.mozilla.org/en-US/",
    "fetchStart": 512398.60101289063
  },
  "incomplete": true
}

In the current process, we don't match these 3 markers. We see that 2 and 3 share their ids, so we should match them, and probably handle the marker 2 as the START for the marker 3. (I'll just do it in a coming patch).

But we don't have any way to match 1 and 2: their ids are different, and their names are different.

I believe this is an important issue as this prevents us from showing the right data to the user.
