Padawan does not autocomplete when inside a multi-line associative array

I have the following code 

``` php
<?php

class A {
    public function foo(){}
}

$a = new A();
// place X
[
    'a' => $a // place Y
];
```

If i try now to type  `$a->` at place X it will work,  but if it try to type `->` at place Y, it will not 
if the array is a multiline normal one , it does work , same for multiline function call
