Different code removed after compression depending on formatting

[shredor]

Describe the bug

After compilation some code is missing. If I change formatting (e.g. add whitespace) everything works well

Input code

const init = () => {
  var e = window.parcelRequire;
  e.register('module1', function () {
    class Hello {
      world() {}
    }
}), e.register('module2', function () {
      console.log('test')
    });
};

init();

  "jsc": {
    "parser": {
      "syntax": "typescript",
      "dynamicImport": true,
      "tsx": true,

SWC Info output

No response

Expected behavior

var e;(e=window.parcelRequire).register("module1",function(){}),e.register("module2",function(){console.log("test")});

If I add whitespace at the beginning of line 7 output becomes correct

Actual behavior

window.parcelRequire.register("module1",function(){});
