Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

Hello! I am tracking this in elm/compiler#1687 because ports and flags allow the same stuff through. The theory is that grouping related things together will help reveal patterns that would not be apparent if issues were just resolved in order as received. Anyway, thank you for reporting this!
