Comment:

 In [changeset:"38649"]:
 {{{
 #!CommitTicketReference repository="" revision="38649"
 Customize: Opt to disable IE8 support via conditional comments instead of
 using unreliable `Array.prototype.indexOf` feature detection.

 Deprecate/remove `WP_Customize_Manager::customize_preview_html5()` and
 remove `document.head` polyfill, both of which were only in place for IE8
 support.

 Props ryankienstra, westonruter.
 Fixes #38021.
