This test requires a medium size course, with around 30 activities and 50 enrolled users, such as the course Activity examples on the QA testing site.

Please test in more than one browser and mention in a comment which ones you've used.

Please test also with at least one RTL language such as Arabic or Hebrew.

1. Log in as a teacher and go to the course, then the gradebook.
2. Move/scroll around the gradebook and confirm:
   • that you can always see the row header and columns
   • that the columns and grades line up with the correct user and activity
   • that floating headers appear at the 'correct' times:
     • The left headers should be visible all time time
     • The footer should always be available if it is present
     • The header should always be visible
     • The various left headers (Overall Average, Controls, and Range if enabled) are always visible

   • Reconfirm above works.

7. Click into a cell
   • Confirm that the cell is replaced with an input field

   .gradeparent .text {

   height: 50px;

   }

9. Click into another field

   • Confirm that the height of the floating username cell was updated too
