This can be a problem because: 1) The URL in the address bar stays as /wp-admin/customize.php?theme=xxxxxxxxx This means you can't see the actual URL of where you are - possibly promoting phishing. 2) You can't live preview any theme you've previously previewed. Steps for reproduction: 1. Preview Theme X 2. Click ""Save and Activate"" 3. Preview Theme Y 4. Click ""Save and Activate"" 5. Try previewing Theme X again, but you will get a blank page now." defect (bug) closed normal 3.4 Customize 3.4 normal fixed has-patch commit
