Don't expand theme title if there are no details to show
|Reported by:||nacin||Owned by:||koopersmith|
If a theme (often a child theme) does not have a screenshot or description, you can still click the "You are now previewing" bit in the customizer, but nothing shows.
Attached patch hides the arrows and prevents it from being "opened". It does not prevent clicking the section to accordion-close everything else.
