 Hi!
 The preview is aligned right, and 20% of the content is missing in the
 view on all themes in the Wp.org directory.

 Here's how you reproduce it:
 1. On a website with WordPress installed, go to the themes tab and click
 "Add new": /wp-admin/theme-install.php?browse=popular
 2. Pick any theme and click "Preview".

 This bug doesn't occur on wp.org when clicking the preview button, only on
 websites with WordPress installed.

 Can't figure how to upload images, but the bug is easy to replicate
 anyways.

 The bug is caused by following CSS:

 {{{
 #customize-container iframe, .theme-install-overlay iframe {
     width: 100vw;
 }

 }}}

 Changing it to follow, fixes it:

 {{{
 #customize-container iframe, .theme-install-overlay iframe {
     width: 100%;
 }

 }}}
