Default values in async function array destructuring miscompiled in ES5 target

[Yeaseen]

Describe the bug

When using array destructuring with skipped elements and default values inside an async function, SWC’s ES5 output shifts elements instead of applying the default. This causes wrong bindings for subsequent variables. Node.js and Babel handle this correctly.

Input code

async function fetchResource() {
  let data = ["John", , 25, "Developer", "California"]; 
  await new Promise(resolve => setTimeout(resolve, 500));
  return data;
}

function func1() {
  return new Promise(async (resolve, reject) => {
    let resource = await fetchResource();
    const [firstName, middleName = "N/A", age, ...rest] = resource;
    
    const result = (function() {
      if(firstName) {
        return {firstName, middleName, age, occupation: rest[0], location: rest[1]};
      } else {
        return {error: "Failed to fetch resource"};
      }
    })();
    
    resolve(result);
  });
}

async function main() {
  const res = await func1();
  console.log(res);
}

main();

SWC Info output

No response

Expected behavior

SWC's ES5 output should print:

{
  firstName: 'John',
  middleName: 'N/A',
  age: 25,
  occupation: 'Developer',
  location: 'California'
}

Actual behavior

But, it actually prints:

{
  firstName: 'John',
  middleName: 25,
  age: 'Developer',
  occupation: 'California',
  location: undefined
}
