List createItems attempts to navigate to the first item before it creates the items

It should not navigate on its own accord.

We need to get rid of this skewed headerlessActiveIndex concept.

The navigator just doesn't "see" items which do not match the selector it is configured with. So it naturally skips things which you do not want to be in the flow. You can put any kind of header or boilerplate elements within a navigable, and it will only navigate among items matching the selector

When navigating using index, it queries only the matching items.

This concept is outdated, but difficult to unpick. @tobiu needs to do it.
