Sentry: Group shows level (and color) of the first issue.

[bruno-garcia]

I'm raising warn events in a retry mechanism. If the last retry happens, I raise a fatal event.

The issues page display the warn color. I assume because the first event to come in was a warning.

When I click on the issue, I see the last event (level fatal) but the color is still of warning:

Maybe I'm wrong to do so but so far I've looked at the colors on the issue list to gauge the _importance_ of an issue.

Closing this issue due to staleness. Feel free to comment here if you think we should still work on this.
