Restore the original rubric navigation

Restore the original rubric navigation

Ref ticket #27407

We used to be able to change the size of the rubric by dragging the central bar left and right. This is now not possible and has had a significant negative effect on the user experience.

The new navigation makes our rubrics almost unusable and has more than doubled the time it takes colleagues to mark assignments.

Please look at this as a matter of urgency, as we are unable to use the rubrics efficiently in their current form. We have spent a lot of time creating detailed rubrics to help the team mark assignments, and the system was working well. Now it is impossible to achieve the marking in the time allotted.

Many thanks.
