I'd say Stockfish also has trouble here.
I run on one core to emulate the speed of a phone (~ 1.7 Mn/s) and it needs 54 seconds (about 100 Mnodes) to find the draw !
That's way too much.
In comparison, Houdini needs 0.1 second, only 300 Knodes.

Some moves are easier to find when you prune less. That's nothing new. But the engine that prunes less will be weaker in most positions.

This is true. My engine OliThink (
http://brausch.org/home/chess ) does hardly any pruning, so finds the stalemate very easily on ply 11. The other side is, that the general search depth is not that great.
Stockfish needs 29 plies.. Now we can gather why it is searching so deep, it misses a lot of moves, which doesn't affect strength a lot.

I think all engines should have a crazy-rook extension : when a king has no move (very rare case) and this side has only rook(s) (rare case) and this side is losing then extend all the possible checks (there are not so many, at most some hundreds) to see if it's possible to force a stalemate.
The algorithm can be more general (not only rooks check): when a king has no move (very rare case) and this side is losing then extend all the possible checks (there are not so many, at most some hundreds) to see if it's possible to force a stalemate.

A similar thing happened once in a slow test game I ran between SF and Tornado 5, where SF took the Rook and allowed stalemate. It was about a year and a half ago, and SF also had trouble seeing the stalemate in analysis mode, but a newer SF may detect it faster, based on what I see in the other replies.

Then, suddenly, and surprisingly, Spike, playing white, stalemated the game in just a few moves. Stockfish completely failed to see the stalemate and avoid it.
I'm ok with 4 seconds here..
