  console.log(1);
}
f()

I can not reproduce this one. I tried Canary and current stable on about:blank and on crbug.com. We have proper RunMicrotasksScope inside Runtime.runScript which we use to run snippets [1].

Could you provide more repro details? Is console by itself responsible? Do we have any context in JavaScript contexts selector in console?

Tried this again. Seems to work now. Weird. Never mind then :)
