We don't have any commands to yank HTML, so we don't display anything,
but I've got code like the following in one of my out-of-tree packages
(which will fail after the fix).  I'm with that, though, but I have no
idea how much other people would be impacted.

(defun ewp-yank-html ()

[...]

  (let ((data (loop for type in '(PRIMARY CLIPBOARD)
		    for data = (x-get-selection-internal type 'text/html)

[...]

      ;; Somehow the selection is UTF-16 when selecting text in
      ;; Firefox.
      (decode-coding-string data 'utf-16-le)
