False positive ? "Equals sign not aligned correctly; expected 1 space but found 5 spaces"

The following code snippet is generating the `Equals sign not aligned correctly; expected 1 space but found 5 spaces` error, while I would expect it to pass without error.

Is it me or did I find another false positive ?

```php
	$options = array( 'min_range' => 0 );
	$key     = filter_var( $key, FILTER_VALIDATE_INT, $options );
```


**Edit:**
This one is a bit awkward: it doesn't generate the error when I use phpcs, however it does when using phpcs *from PHPStorm*. Both use the same sniffs as synchronized with the current repo. Very weird indeed.
