This means that some Chrome browsers already have the "Referrer Policy: Default to strict-origin-when-cross-origin" feature flag enabled by default. As a result, when those users launch New Quizzes, the "Return" button takes users to the course homepage, instead of the index page used to access the quiz.
The "Return" button should return user to the index page used to access the New Quiz.
Steps to Reproduce
Prerequisites: A course with New Quizzes enabled and a New Quiz
Go to chrome://flags/#reduced-referrer-granularity - ensure it is enabled
Launch the New Quiz from a page that is not the homepage (Assignments, Quizzes, Modules ect)
Use the return button - note that you are returned to the Course home page
