 The Theme Customizer allows you to click links within the preview to
 navigate to other URLs to customize. Navigation within the preview is
 especially important now with the Widget Customizer, since many templates
 display render widget areas, and you may have to navigate to another URL
 in the preview to edit that template's widget areas.

 When you navigate, however, the URL in the parent window does not update
 to reflect the URL inside of the preview. If the Customizer was first
 invoked from http://example.org/test-page/ then the URL in the Customizer
 will remain http://example.org/wp-
 admin/customize.php?url=http%3A%2F%2Fexample.org%2Ftest-page%2F no matter
 how much navigation is done in the preview. This makes it difficult to
 deep-link in the Customizer preview.

 Additionally, you cannot currently use the browser's back button to return
 to the previously URL previewed in the Customizer.

 To address the above usability problems, the Customizer should implement
 `history.pushState` and the `popstate` event. Some support for these were
 added when invoking the Customizer from for a theme preview, but it was
 only implemented to add support for exiting out of the Customizer via the
 back button. See [20488] for #20337.
