invalid code is generated if a semicolon is omitted after setting a property on an object to an arrow function on the line before an iife

[LinusCenterstrom]

The original code is generated by webpack (can provide if wanted).

But a minimal example is this.
source:

const a = {};
a.g = () => {}
(function(){
  console.log("test");
})();

output:

const a = {};
(a.g = () => {
})(function() {
  console.log("test");
})();

From what I could gather defining an arrow function should cause automatic semicolon insertion which is why the source is even valid in the first place.

Thanks so much for reporting this. Will fix.
