Repeated indices in CSL selectors produce inconsistent shapes.

>> data = struct(a={10, 20});
>> result = mpath.resolve(data, "/a<1,2,1>", MissingPolicy="retain")

result =

  2x1 mpath array

    /a<1>
    /a<2>

The expected result is 3x1, each with the three respective CSL selector indices.

In contrast, having just the index 1 repeated gives the expected result:

>> result = mpath.resolve(data, "/a<1,1>", MissingPolicy="retain")

result =

  2x1 mpath array

    /a<1>
    /a<1>

>> result = mpath.resolve(data, "/a<2,2>", MissingPolicy="retain")

result = 

  mpath: /a<2>

The second case here would expect the same element but repeated as a 2x1.

In contrast, having just the index `1` repeated gives the expected result: ```matlab >> result = mpath.resolve(data, "/a<1,1>", MissingPolicy="retain") result = 2x1 mpath array /a<1> /a<1> >> result = mpath.resolve(data, "/a<2,2>", MissingPolicy="retain") result = mpath: /a<2> ``` The second case here would expect the same element but repeated as a 2x1.
