- Old behavior: each page with such a modifier was first set
invisible at creation of the InvisibiliyChanger attached to
it, and then, after domain evaluation, the page was reset
to visible if needed.
- New behavior: wait for the domain evaluation to decide to set
a page invisible. It also fixes a bug when 2 pages where
active simultaneously. Moreover, we only switch to a newly
displayed page if we are in edit mode (use case: we edited
a field making the page's domain true, so we want the user
to pay attention to this page).
