Comment (by azaozz):

 From the post linked in the ticket:

  "This usually won’t be a problem, but if you have your frontend servers
 behind a proxy or load balancer that strips the user agent..."

 WordPress has to detect the user agent to properly output the textarea
 content depending on which editor is loaded first. It also doesn't make
 sense to load TinyMCE in browsers that don't support it.

 It is possible to add an exception in `user_can_richedit()` for this
 particular case. However the user agent is used in several other places to
 adjust the output, most notably in `wp_is_mobile()`. It is not possible to
 make the right assumption in these cases.
