Arrows not correct with JSON or YAML Big Data [Smetana]

Question

Hello PlantUML team,

Here are some other examples, where arrows are not correct (with JSON little Big Data), see arrows between coloured field that sticks or intertwines:

1/ First example

@startjson
[
{"k1": "v1", "k2": "v2","k3": "v3"},
{"k1": "v1", "k2": "v2","KO": "v3"},
{"k1": "v1", "k2": "v2","KO": "v3"},
{"k1": "v1", "k2": "v2","k3": "v3"},
{"k1": "v1", "k2": "v2","k3": "v3"},
{"KO": "v1", "k2": "v2","k3": "v3"},
{"KO": "v1", "k2": "v2","k3": "v3"},
{"k1": "v1", "k2": "v2","k3": "v3"}
]
@endjson

2/ Second example

@startjson
[
{"k1": "v1", "KO": "v2","k3": "v3"},
{"k1": "v1", "KO": "v2","k3": "v3"},
{"k1": "v1", "KO": "v2","K3": "v3"},
{"k1": "v1", "k2": "v2","k3": "v3"},
{"k1": "v1", "k2": "v2","k3": "v3"},
{"k1": "v1", "k2": "v2","k3": "v3"},
{"k1": "v1", "KO": "v2","k3": "v3"},
{"k1": "v1", "KO": "v2","k3": "v3"},
{"KO": "long long long long long long long long long v1"}
]
@endjson

3/ 3rd example

@startjson
[
["ok"],
["KO"],
["KO"],
["KO"],
["ok"],
["ok"],
["ok"],
["ok"],
["ok"],
["ok"],
["ok"],
["ok"],
["ok"],
["KO"],
["KO"],
["KO"],
["ok"]
]
@endjson
