Retain submission list page position when returning from individual grading view

When grading assignments with multiple pages of student submissions, clicking into an individual student’s submission and then navigating back returns the instructor to page 1 instead of the original page they were on. Current behavior: Instructor is on page 5 of submissions →opens a student’s submission → clicks back → lands on page 1. Expected behavior: Instructor should return to page 5 (the same page they came from).
