Generic.WhiteSpace.ScopeIndent: Indentation doesn't get fixed inside closures as a callback arg in a function call

[yCodeTech]

Describe the bug

If a closure/anonymous function is used as a callback in a function call, then indentations doesn't get fixed with Generic.WhiteSpace.ScopeIndent sniff property exact set to true. The conditional statement blocks will get fixed, but the code inside them won't. Both space and tab indentation doesn't get fixed. I am aware there is multiple closed issues relating to indentation but they're slightly different issues I believe (none of the solutions fixed the issue).

Code sample

some_function(function ($arg) {
    if (!$arg) {
                      return;
    }
                            $arg = "Hello";
		return $arg;
});

To reproduce

Steps to reproduce the behavior:

1. Create a file called test.php with the code sample above...
2. Run phpcs test.php ...
3. No error message outputted.

Expected behavior

The indentation should be fixed no matter its type. So above code should be fixed to:

some_function(function ($arg) {
    if (!$arg) {
        return;
    }
    $arg = "Hello";
    return $arg;
});
