Bug: Data are displayed partly sorted

[manitu-opensource]

Current version of jsonovich (Firefox current) makes input

{
    "2017": {
        "08": {
            "count": 23
        },
        "09": {
            "count": 21
        },
        "10": {
             count": 34
        }
    }
}

getting displayed as

{
    "2017": {
        "10": {
             count": 34
        },
        "08": {
            "count": 23
        },
        "09": {
            "count": 21
        }
    }
}

Thanks for the bug report, I can reproduce.

Unfortunately this is to be expected for several reasons:

1. "An object is an unordered collection of zero or more name/value pairs" according to the JSON RFC.
2. The JSON string is parsed into a JavaScript object before formatting and the order of properties when iterating over JS objects was until recently unspecified. The ordering defined in ES2015 is not always insertion order but would by chance be what you expected in the above case.
3. The formatter iterates over the object properties in a way that is still unspecified even in the latest ES2018 draft anyway.

I'm not sure if I should try to fix this since the JSON spec itself states that objects are unordered. It may be possible, but I'll have to assess the costs when I'm rewriting the formatter.

Sorry for the noise, wrong issue number in commit message.
