broken output code: ReferenceError: x is not defined

[milahu]

Describe the bug

i am throwing wakaru at a 3MB file bx-progressivewebapp.js
preprocessed with webcrack -- same input code as in #110

the output code produces the runtime error

ReferenceError: bbb is not defined

Input code

let bbb = aaa.target;
let ccc = bbb.parentElement;

Reproduction

No response

Steps to reproduce

No response

Expected behavior

input

let bbb = aaa.target;
let ccc = bbb.parentElement;

transform 1: replace bbb with target

let { target } = aaa;
let ccc = target.parentElement;

transform 2: replace ccc with parentElement

let { target } = aaa;
let { parentElement } = target;

Actual behavior

let { target } = aaa;
let { parentElement } = bbb; // FIXME ReferenceError: bbb is not defined

i guess the problem is that the 2 transforms happen in parallel

and/or these are 2 separate transforms

similar

currently, wakaru produces this diff

       {
-        let al = aj.currentToken;
+        let { currentToken } = aj;
         aj.read();
         if (aj.currentToken.tokenType === "EOF") {

expected: also replace aj.currentToken with currentToken

edit: probably no. aj.currentToken can have side effects that are required
