 In the customize preview, external links get a `cursor: not-allowed`. Core
 audio playlists link individual tracks within the playlist list to the
 individual audio file (.mp3, etc.). This is likely the case as a fallback
 for no-js users. Since the customize preview requires JS, clicking these
 links will not actually navigate the customize preview off of the site,
 and they will instead operate the playlist. Users should be encouraged to
 interact with playlists in the preview, as they may be adding them within
 content via Customize Posts or in a widget via a plugin such as Featured
 Audio.

 Suggested solution: add something along the lines of `if (
 element.hasClass( 'wp-playlist-caption' ) { return: false; }` somewhere in
 `wp.customize.isLinkPreviewable()` in `wp-includes/js/customize-
 preview.js`.

 This needs an actual patch and more thorough testing. There may be other
 similar situations where we shouldn't use `cursor: not-allowed` that could
 be grouped into this ticket if desired.
