Alexander Korotkov bd6366129b Document behavior of the .** jsonpath accessor in the lax mode ... When the .** jsonpath accessor handles the array, it selects both array and each of its elements. When using lax mode, subsequent accessors automatically unwrap arrays. So, the content of each array element may be selected twice. Even though this behavior is counterintuitive, it's correct because everything works as designed. This commit documents it. Backpatch to 12 where the jsonpath language was introduced.
