Problem: The 'Pages' text input box suggests and accepts for 11 or more pages, when the maximum is 10. These are rejected on submission, but this is bad design.
Acceptance criteria
- The error messages should continue to appear if the admin somehow manages to get these through
- The 'Pages' input field should not suggest more than 10 pages
- The 'Pages' input field should not accept more than 10 pages
Note that we may adjust the maximum value in the future: T202776: Determine then implement page limit for partial blocks
Notes: TagMultiSelect should have a limit. Needs to be fixed in upstream OOUI.
