Bug in obfuscate js code.

First at all, sorry for my english, i will try to explain it as better as possible.

I have the following js code:

```javascript
export const Painter = function (elements, data) {
let title = elements.title;
let container = elements.container;
this.prePaint = () => { };
this.paint = () => { };
this.postPaint = () => { };
let finalPaint = () => {
this.prePaint = () => { };
this.paint = () => { };
this.postPaint = () => { };
createPromise();
};

let createPromise = () => {
return new Promise((resolve, reject) => {
this.paint = () => { resolve() }
}).then(() => {
this.prePaint(elements, data);
title.innerHTML = data.title;
container.innerHTML = data.html;
this.postPaint(elements, data);
finalPaint();
});
}

createPromise();
};
```

When i obfuscate this code, it seems like this (it was minimized and formatted by the browser):
```javascript
5: [function(a, b, c) {
"use strict";
Object[_0x56ae("0x6")](c, _0x56ae("0x6e"), {
value: !0
});
c[_0x56ae("0xb5")] = function(a, b) {
var c = this
, d = a[_0x56ae("0xb6")]
, e = a[_0x56ae("0xb7")];
this.prePaint = function() {} //// THIS LINE
,
this[_0x56ae("0xb8")] = function() {}
,
this[_0x56ae("0xb9")] = function() {}
;
var f = function() {
c[_0x56ae("0xba")] = function() {}
,
c.paint = function() {} ///// THIS LINE TOO
,
c.postPaint = function() {} ///// AND THIS LINE TOO
,
g()
}
, g = function() {
return new Promise(function(a) {
c.paint = function() {
a()
}
}
)[_0x56ae("0x24")](function() {
c[_0x56ae("0xba")](a, b),
d.innerHTML = b[_0x56ae("0xb6")],
e.innerHTML = b[_0x56ae("0x34")],
c.postPaint(a, b),
f()
})
};
g()
}
}
, {}]
```

You can see, how the fisrt this.prePaint has not transformed to this[_0x56ae("0xba")] and when this is called, it said undefined function.
But if i insert breaklines between all this "problematic" lines, it work. Like this:

```javascript

export const Painter = function (elements, data) {
let title = elements.title;
let container = elements.container;

this.prePaint = () => { };

this.paint = () => { };

this.postPaint = () => { };

let finalPaint = () => {

this.prePaint = () => { };

this.paint = () => { };

this.postPaint = () => { };

createPromise();
};

let createPromise = () => {
return new Promise((resolve, reject) => {

this.paint = () => { resolve() }

}).then(() => {
this.prePaint(elements, data);

title.innerHTML = data.title;
container.innerHTML = data.html;

this.postPaint(elements, data);

finalPaint();

});
}

createPromise();
};
```

I did fix this issue with this partial solution, but i don't know where more places of my code, will appear the same issue.

Thank you

Aucun fichier du dépôt, test, version ou configuration n’est indiqué. Commencez par reproduire l’exemple Painter fourni via le pipeline d’obfuscation gulp et comparez les références générées pour this.prePaint, this.paint et this.postPaint. C’est terminé lorsque le code obfusqué conserve les références de propriétés appelables sans nécessiter l’insertion de sauts de ligne.
