Minor Pharah (possibly echo) Bug

In a recent Mystery heroes game on New Queen Street, I was playing as pharah, dueling an echo who had duped ana. i lost, it happens. however, the kill feed classified it as a self damage kill, even though when i checked the vod, i had no shots anywhere near me. What i did notice was that echo had landed a shot into me and was reverting when i died, with the DoT still ticking down. i have the vod code and the timestamp here
VOD code: SZ163V
timestamp: 8:02/8:03
