 In #32637, we based the action of the Customizer close button on the
 referring URL. However, if the login URL is accessed on the way to the
 Customizer, this results in a mess of redirects and confusing behavior for
 the user (while also inducing fear that their changes were not
 saved/published).

 The main reason I opened #32637 in the first place was for when someone
 has a Customizer link bookmarked or enters it directly; however, these are
 the very situations where they are most likely to need to log in first,
 causing this bug.

 There are two options for fixing this behavior - adding something to
 prevent the login page from being accessed explicitly, or removing the
 behavior of trying to find the referrer entirely in favor of the preview
 URL and/or home URL fallbacks. It would probably be better to go with the
 first option, although my concern with that approach is that there may be
 other cases like that where returning to the referring URL causes
 problems.
