Description

Not a huge user of the sieve command. Anyway: I notice that by default the command string is filled with the ``-mask`` parameter that takes the same input layer. There is no way to remove ``-mask`` from the command. Even if ``-nomask`` is selected, ``-mask`` is taken into account when running the algorithm.

Trying with the attached layer, the sieve command gives correct result when from the command line ``-mask`` is removed (other parameters are `Threshold = 8`, `Use 8-connectedness = True`)
