Broken private fields in classes (JS)

[MikeDombo]

Description

Private fields in JS classes use # as part of the identifier name. When beautifying the initial declaration, this library puts it on the wrong line.

Input

The code looked like this before beautification:

class X {
    #__private = null;
}

Expected Output

The code should have looked like this after beautification:

class X {
    #__private = null;
}

Actual Output

The code actually looked like this after beautification:

class X {
    #
    __private = null;
}

Steps to Reproduce

So what's the solution for this?
