The preview in customizer (customize.php) causes a warning message in the browser console:

An iframe which has both allow-scripts and allow-same-origin for its sandbox attribute can remove its sandboxing.
Content Security Policy: Ignoring ‘x-frame-options’ because of ‘frame-ancestors’ directive.

I cannot reproduce this warning testing in Chrome with a local site, on a site with SSL, and on a multisite without SSL. Can anyone else identify situations that appear to trigger this warning?
