Threefold / Fivefold repetition rule

[peterseeberg]

Not sure if this is a bug or a potential improvement.
When replaying / learning from played games, moving on from suggested better moves, following the Stockfish proposals for both Black and White, it happens quite regularly that moves are repeated over and over, such that according to my understanding the Threefold Repetition rule applies - a player may claim a draw if the same position occurs three times during the game - or later the Fivefold Repetition rule - requiring - if there was - the arbiter to intervene and declare the game drawn if the same position occurs five times.
Not sure if the responsibility for this bug (?) or improvement (include an IF "position" variable = 3 then... write on screen: THREEFOLD REPETITION / FIVEFOLD REPETITION / DRAW or something) lies with Lichess or Stockfish developers?
