Comment:

 In [attachment:36793.diff]:
 * Remove use of reserved word `default` in Underscore template which
 breaks IE8.

 This code was introduced in r30712 and is in`class-wp-customize-media-
 control.php` - not sure why this cropped up in 4.5 specifically, perhaps
 something in the customizer load sequence is now using the media control
 (site logo?) that wasn't previously being used.

 This change fixes the issue. Screenshot showing no errors in customizer in
 IE8:
