i18next: Problems with plurals >= 3

Hi! I have some problems with plurals. I’m Russian, and our language has 3 plural forms: single, multiple for x2–x4 except x11–x14, that work like other multiple plurals. And sometimes I need to use parts for text formatting, like <a> or <mark> tags around some words. So, I split my text like this:

locales/ru/common.json

{
    "SomeTextKey": {
        "part0": "Укажите, пожалуйста",
        "part1": "не менее",
        "part2": "предметов.",
    },
    "SomeTextKey_0": {
        "part0": "Укажите",
        "part1": "не менее",
        "part2": "предметов.",
    },
    "SomeTextKey_1": {
        "part0": "Укажите",
        "part1": "не менее",
        "part2": "предмета.",
    },
    "SomeTextKey_2": {
        "part0": "Укажите",
        "part1": "не менее",
        "part2": "предметов.",
    }
}

So, part2 depends on count.

I use React+ES7 syntax and your react-i18next plugin, so, in my component, I use this translation like

@translate(['common'])
export default class MyComponent extends React.Component {
    render() {
        const {
            count,
            t,
            valid,
        } = this.props;

        return (
            <div>
                {t('SomeTextKey.part0', { count })}
                <mark className={`mark ${valid ? 'mark_no-style' : ''}`}>
                    {t('SomeTextKey.part1', { count })}&nbsp;{count}
                </mark>
                {t('SomeTextKey.part2', { count })}
            </div>
        );
    }
}

This should look like: Укажите не менее 0 предметов. Укажите не менее 1 предмета. Укажите не менее 2 предметов. … Укажите не менее 22 предметов.

and so on…

Docs for plurals said that I need only plural keys (0, 1, 2). But this doesn’t work. If I specify the default key, it works, but without plurals, because I get

Укажите, пожалуйста, не менее 1 предметов.

I used word ‘пожалуйста’ to know, if plurals don’t work. And there it is, sadly.
