Draw by insufficient material or draw by stalemate?

Earlier this year I played a game against one of my friends on Chess.com and the final position after 64...Nxc7 65. Bxc7 was like this.

 

 

In your opinion, do you think Chess.com ruled the position in the game as a draw by insufficient material or a draw by stalemate? Clearly both rulings are valid for the position. Chess.com does not declare two rulings at the same time though.

My guess is stalemate but it just depends on which gets checked first in the code.

In the actual game it was declared draw by stalemate, which came as a shock to me in the game because I had expected a draw by insufficient material (clearly after Bxc7 - sorry I put the diagram axes wrongly, the final move is indeed Bxc7 - it was a case of insufficient material since king and bishop versus bare king is an instant draw in all positions), and both my friend and me forgot completely that the final position happened to be stalemate.

 

I still prefer the position to be declared draw by insufficient material though, just as a king and knight versus bare king endgame would.

I would say a draw by stalemate, because in the first King + Bishop vs. King + Knight is already insufficient to win. Therefore it must be a draw but Chess.com didn't close the game until the bishop ate the knight, so that means the game is drawn by stalemate.

The game does not end at that point as technically there are ways to win the game for either player while the time has not run out yet. King and knight versus king and bishop is not a draw yet until one of the pieces have been captured or the time runs out (in FIDE rules, the player whose time has run out first loses, but Chess.com declares this a draw). The final position happens to be both a draw by insufficient material and a draw by stalemate.
