Para recrear esto necesitas hacer algunas de las anteriores acciones y justo darle al F11 y esto se quedara bugeado infinitamente, por ejemplo si haces esto con el salto saltaras infinitamente hasta que toques denuevo la misma tecla.

Thank you for the report. However, this issue is a duplicate of MC-1519. This bug was fixed in the 1.13 snapshots (although it still affects 1.12.2).
Please note that we can only take reports in English; in this case I was able to understand well enough what you were saying but not everyone here can.
