Describe the bug
In the compiled output, instead of calling the function, the function body is returned.

In the screenshot:
Upper left: source code
Bottom left: swc cli compiler output
Upper right: running source directly in browser, output is correct
Bottom right: running compiled code directly in browser, output is wrong

Input code

const myVar = {
  target: {
    value: "ABC"
  }
}

console.log(myVar.target.value.toLowerCase?.());

Config

No config. Running CLI from command line without any flags.

npx swc example.ts

Expected behavior
The console log should output abc

Version
The version of @swc/core: "1.2.76"
