Localization of one-dimensional arrays

[RinkAttendant6]

The localizeArray function does not allow localization of flat arrays:

{
    "arrayGroups": {
        "bar": {
            "en-CA": "bar_en",
            "fr-CA": "bar_fr"
        }
    }
}

$foo = array(
    'bar_en' => 'good morning',
    'bar_fr' => 'bon matin'
);

$l10n->localizeArray($foo, 'bar', 'fr-CA');

Expected:

$foo = array(
    'bar' => 'bon matin'
);
