How did I get Healing Done as D.Va?

I played some Total Mayhem. This was my end card:

...how did D.Va get any healing done at all? Is it her ultimate?

The game made me this highlight from the match. You can see the health go up by 13 exactly at the very end, though this might be entirely a coincidence.

It appears that when D.Va deletes a Moira's Biotic Orb with Defense Matrix, she gains ownership of it for a split moment. Any healing that the orb is doing at the time of it being deleted is credited to D.Va.

A similar, but rarer bug has been around for a long time and is known to affect Junkrat as well. I am not sure about the causes of that one, but it seems related to getting healed while calling a new MEKA.
