We need some way to prevent components from being unregistered if they're not contained in the parent component DOMNode about nimbly HOT 2 OPEN

Proposed rules for component refresh clean-up:

1. If component XYZ is not contained in the DOM, then
   A. If component XYZ is registered into a repeatable section AND the repeatable section is still present, then component XYZ gets unregistered.
   B. Else if component XYZ does not belong to a repeatable section and there was another (newer) component registered using the same tag name, then component XYZ gets unregistered (because the new component replaces it).
2. If component XYZ is contained in the DOM, then it does not get unregistered.

This could be more easily solved by ignoring the unregistration and deletion of components that are registered outside of the ._render method.
