function with for...in or for...of removed during tree-shaking

[Zirro]

I've extracted a minimal testcase that reproduces the issue in Rollup 0.34.9:

const items = document.querySelector('.items');

function sayHello() {
  for (const item of items.children) {
    item.textContent = 'Hello!';
  }
}

sayHello();

The function remains after tree-shaking if I remove the loop but keep the .textContent-line, or add more code such as a console.log() into it.

Having looked at issue #786, I believe the cause might be the same. Feel free to close this issue as a dupe if you can verify that this is the case.

Sorry for the delay – fixed in 0.35.4
