Steps to reproduce:
- Login to backoffice.
- Go to Admin / Roles.
- Click on one of functional button - "Assign to Users / Groups", "Copy" or "Edit".
- Verify right side menu appearance.
Right side menu at the bottom has too short edge.
Right side menu edge at the bottom (Discard changes button) should be the same like at the upper side (Save button).
The problem exist also on each "edit" view in Admin section.
