- We should make it as if the user pressed enter when they tab out or lose focus of this widget.
- If the page name is invalid (e.g. redlink) an error message/state can appear either before or after the admin submits the block
- If the page name is a duplicate of a page already provided, it can be discarded with no error message
- If the page is the 11th (the current max is 10) an error message/state can appear either before or after the admin submits the block
