Write a function. Test real cases. Improve your solution.
Given tickets with an id string and status string, return an array of {status, ids} groups. Group order follows the first appearance of each status; ids inside each group follow input order. Status comparison is case-sensitive and every string, including an empty string or "__proto__", is valid. Preserve duplicate ids. Do not modify the input.
