[BUG] When alerts are grouped, the card does not differentiate between status firing and resolved

[bvanelli]

Describe the bug

This happens because of an (oversight?) on alertmanager. It apparently groups the messages to send them all at once, but there can be entries which are resolved in between those messages:

{
   "alert":{
      "receiver":"prometheus-msteams",
      "status":"firing",
      "alerts":[
         {
            "status":"resolved",
            "labels":{
...

If at least one status is firing, then the whole alert status is set to firing. And since they are grouped in the same message and this "status" is not provided as label, it will then display on the default template as triggering, when in fact it isn't.

There is some discussion on the prometheus repo I'll also link:

prometheus/alertmanager#2334 (comment)

Version

Using latest 1.3.4

To Reproduce

Maybe I can craft an example request to reproduce it later.

Expected behavior

It should either:

• Remove the resolved from the list when displaying the alert or
• Even better, separate the alerts into two distinct messages, so that one of them only shows the still firing and the other the
