AbstractArraySniff produces invalid indices when using ternary operator

[michalbundyra]

Example:

<?php

$array = [
    'foo' => 'foo',
    'bar' => $baz ? ['abc'] : ['def'],
    'baz' => 'baz',
];

Indices:

Array
(
    [0] => Array
        (
            [index_start] => 9
            [index_end] => 9
            [arrow] => 11
            [value_start] => 13
        )

    [1] => Array
        (
            [index_start] => 17
            [index_end] => 17
            [arrow] => 19
            [value_start] => 21
        )

    [2] => Array
        (
            [value_start] => 31
        )

    [3] => Array
        (
            [index_start] => 37
            [index_end] => 37
            [arrow] => 39
            [value_start] => 41
        )
)

Above is dump of variable $indices in method AbstractArraySniff::processMultiLineArray.

It is wrong, because array contains 3 elements, all 3 with keys.
The problem is because of ternary operator.
