Incorrect lookup of parent node for % operator

[eschava]

Please check the example below
Data:

[{
   "parent": "a",
   "children": [{ "child": "c1"}, {"child": "c2"}]
}, {
   "parent": "b",
   "children": [{"child": "c1"}]
}]

Query

$.children.{'parent': %.parent, 'child': child}

produces

[ {
  "parent" : "b",
  "child" : "c1"
}, {
  "parent" : "a",
  "child" : "c2"
}, {
  "parent" : "b",
  "child" : "c1"
} ]

So for the first child of the "parent:a" node it finds another parent (perhaps because the child node is absolutely equal)
