Comment:

 In [changeset:"39227"]:
 {{{
 #!CommitTicketReference repository="" revision="39227"
 Customize: Use selective refresh for custom header changes when possible.

 * Use `postMessage` transport for header image settings by default when
 video headers are supported, and thus `the_custom_header_markup()` will
 necessarily be used (and thus a selective refresh partial will be
 available).
 * Ensure that `the_custom_header_markup()` always outputs a container
 element in the customizer preview even if the header is empty.
 * Ensure that edit shortcut appearing for custom header does not get
 positioned off-screen.

 Props bradyvercher, westonruter.
 See #38639.
 Fixes #38737.
