issue prettifying (function(){code();{code}})()

[divinity76]

Description

the code does not look pretty after "prettifying"

Input

The code looked like this before beautification:

(function() {
  	some_code_here();
    {
        /* IE11 let bug bypass */
        let index;
        for (index in a) {
            a[index];
        }
    }
})();

Current Output

The code actually looked like this after beautification:

(function() {
    some_code_here(); {
        /* IE11 let bug bypass */
        let index;
        for (index in a) {
            a[index];
        }
    }
})();

Expected Output

The code should have looked something like this after beautification:

(function() {
    some_code_here();
    {
        /* IE11 let bug bypass */
        let index;
        for (index in a) {
            a[index];
        }
    }
})();
