 Steps to demonstrate:

 1. Open the Customizer, make a change, and save your changeset as a draft.

 2. Open the Themes panel, discover that you can't preview themes while the
 changeset is a draft, and switch the changeset status back to "publish."

 3. Go back to the Themes panel, discover that you now can preview themes
 again, and preview a new theme.

 4. Decide you don't like the new theme, and go back to the Themes panel to
 preview another theme or go back to the active theme.

 5. Get the "Sorry, you can’t preview new themes..." error.
