[OPEN] User details tray doesn't open with anonymously graded assignments

Engineers are currently investigating the issue.
Description
When an anonymous grading assignment has a grade, but not posted yet, it prevents the user details tray from opening on the People page.
Expected Behavior
Instead, the tray should open regardless of an assignment grade being unposted.
Workaround
No workaround exists at this time.
Steps to Reproduce
Prerequisite: Published course with the Anonymous Grading feature flag enabled, and a student.
-
Create an anonymous grading assignment.
-
Give the student a grade but leave the grade unposted.
-
Navigate to the People page and try to click the name of the student that was just graded.
-
Notice the tray on the right side tries to open but closes instantly.
