Has anyone else noticed a change in how the wherecontains function works?
Specifically if I am searching for repeated values the wherecontains now removes duplicates from the results where it used not to.
Eg:
wherecontains({a, b, a}, {a, b, c})
I expect this to return [1, 2, 1] however it now returns [1, 2].

If this is the desired behavior does anyone know how I might get the first result (IE: [1, 2, 1]) short of using an apply function? (I'm manipulating large arrays and I'd prefer to use a set function instead of an iterative one)...
