Feature Request: Enable Analysis board after puzzle

I'm bad, so i get the puzzles wrong.

e.g lichess.org/training/115587

I cannot understand why this puzzle has the answer it does.

The solution doesn't really explain why it is the answer. I could probably investigate but the pathway of the puzzle is 'fixed' once complete.

Once the puzzle is complete (failed), it would be nice to analyze the solution proposed.

e.g. IN the puzzle above, i dont see what the next steps are when white doesn't respond with the move given in the solution

After you have seen the correct answer, switch on the Stockfish, reverse the moves and try alternative moves. ?

I know what you mean when you say "the pathway is fixed once complete". This is only true if you failed the puzzle, though.

The work-around I use is after I see the correct solution, I refresh the browser page, put in the correct response, and then turn on Stockfish and try alternative moves. That should work.
