Comment (by flixos90):

 I have implemented https://github.com/WordPress/wordpress-
 develop/pull/5574 as a fix for this bug. It addresses the root problem and
 through that the concrete broken user experience reported: With the PR
 applied, the Customizer-previewed theme's data is correctly loaded,
 without any data from the original theme bleeding over.
