We have been recently receiving reports of "Grade" links pointing to the wrong students.

This is an issue that was reported multiple times in the past (and potentially fixed MDL-42306, MDL-44330) however still present.

Steps to reproduce:

1. Enroll a few students into a course
2. Setup an assignment and add file submissions
3. As a Teacher (or higher role) got the assignment grading table
4. Leave filters unset
5. In the browser, duplicate or open the page (Tab 1) in a new tab (Tab 2)
6. Select First and Last Name letter filters 
7. Go back to Tab 1 and click "Grade" on a student row
8. See the name in the submission page does not match the student's name in the row

Expected behavior:
When I click on the "Grade" button on a student row, I open the submission for that student no matter what filters are selected in any browser tab.

Actual behavior:
When I click on the "Grade" button on a student row, I open the submission of the student in the same row position in the tab where I last applied the filters NOT the student I am clicking on.

Example:

The following example shows the issue on a local installation of Moodle 4. However, this was first identified and reproduced on our live server.

Step 1: In Tab 1 I have the submissions page open with no filters selected, the first row shows student named Admin:

Step 2: In Tab 2 I open the same page but filter the students by name, now the first row shows a student named Student Two:

Step 3: When I go back to Tab 1, and I click on the "Grade" button that corresponds to Admin, the submission of Student Two is opened instead:
