Comment (by dd32):

 After looking at an example of this, it's kind of weird.

 The media templates are being output on the page by a plugin, and the
 updater redirects before the page is fully loaded.
 Because the page redirect occurs before the entire page is loaded, the
 page load is severed, and the contents of the partially loaded `<script
 type="text/html">` gets output on the page as the redirect occurs.

 Several fixes:
 1. Don't redirect, or redirect upon DOM ready instead
 2. Output a `<div class="hidden">..` element last to hide all further
 output
 3. Plugins shouldn't enqueue stuff on all pages

 The problem is that all 3 are not ideal, and don't provide a good UX.
 We want to redirect the user ASAP, Outputting a div to hide all further
 output feels hacky, and we can't control plugins..
