Steps to reproduce
- Go to Content > Forms
- Add a Form
- Add a text field named Text 1
- Add a rule
- Leave conditions blank for now
- Add action: jump to page 1
- Add condition now: if Text 1 is not empty
User should not be able to perform a jump to page when there's only one or two page. And this should be somehow explicit to him.
The page selector at the jump to page action gets blank, seeming like a bug.
