We had a bug regarding the un-expanded view of TA grading not matching the student view. The bug meant that any and all marks for a given problem in a gradeable would still be displayed upon clicking 'save'.

The intended behavior was to only display marks given to the student for this problem, along with any marks designated "Show to all" , once 'save' is clicked.

This problem was fixed in PR# #12131 .

Next, we should add a Cypress test to ensure this error does not occur again in the future.
