Have a form view with a notebook.
In the notebook a page has autofocus, and is also invisible in some
circumstances.
Before this commit, the default page was always displayed, even if invisible,
its anchor was not selected though.
After this commit:
- if the default page is visible, display it.
- if the default page is not visible, select the first visible page
- if the default page was visible and the page has changed, don't select the default page at next render
- if the default page was not visible and becomes visible, select it at next render
