Comment (by westonruter):

 I believe I've nailed down the problem. In the latest patch
 [attachment:27767-07.patch 27767-07.patch]:

  * Run `retrieve_widgets()` earlier, and only when initially opening
 customizer in a theme switch. (The results of this function get passed
 along subsequently by Customizer POSTs.)
  * Likewise, initially filter `sidebars_widgets` option to be the
 retrieved widgets. This restores any widget area configuration previously
 used on the previewed theme.
  * Store the old theme's `sidebars_widgets` in a new customizer setting
 which gets supplied into the `sidebars_widgets` theme mod after theme
 activation.
