Bug with the candles on a cake

If you place a candle on a cake and click on the candle. Then you can get an infinite amount of candles if you klick on the candle on the cake. So you can dupe easily candles if you place a candle on a cake. I played on my own server on this snapshot and so that worked I think it works too in singleplayer. My Ingamename is RAT_Ratte.
