Unexpected (unhelpful) autocomplete suggestions inside function call when spreading an array

<!-- Please try to reproduce the issue with `typescript@next`. It may have already been fixed. --> **TypeScript Version:** 3.2.1 <!-- Search terms you tried before logging this (so others can find this issue more easily) --> **Search Terms:** spread autocomplete **Code**  I'm not 100% sure what causes this, but its reproducible in this project even after closing VSCode. I don't think it has to do with the error below, as that vanishes when I delete the line: https://github.com/AlCalzone/create-adapter/blob/65e5f59ce824a9f405c441091d3d7fad13ee70b5/src/lib/questions.ts#L104 **Expected behavior:** No autocomplete **Actual behavior:** This super unhelpful autocomplete  **Playground Link:** nope **Related Issues:** nope
