Research how Experience Builder previews content

Problem/Motivation

There are rumblings in the Drupal-sphere about how Drupal Core's preview logic may change as a result of the advancements made by experience builder. Two key inventions are leading this charge

1. Workspaces are now stable
2. Experience builder's React-driven preview experience is lightyears beyond anything we've had before

Together they appear to change both the backend and frontend experience for previews. We should monitor their progress and look for a way to reuse their progress in same page preview.

Even in this experience builder driven future, I can still see a purpose and role for Nodes. And as long as we have Nodes we may still have a need to preview just the node, outside of the context of the page a node may be laid out in.
