Grade icons in Gradebook's Grade Summary and Student Review Mode screens do not match actual tool icons

Use a site with Gradebook, Assignments and Tests & Quizzes. Create an assignment and send the grade to the gradebook. Post the assignment. Create a one-question quiz and send the grade to the gradebook. Publish the quiz. Click into the Gradebook spreadsheet. Observe the grade item icons in the spreadsheet next to those scores that are coming from Assignments, and T&Q. Click on a student's name/link in the spreadsheet. Notice that the grade item does not have Assignment's paper icon next to it here; it displays a puzzle icon. The quiz does not have T&Q's checkmark here; it displays instead the puzzle icon. Expected: the grade item from Assignments and T&Q will have the tool's designated icon next to the item title in all windows of Gradebook.
