 Seems line breaks have to be normalized when saving edited files. Also if
 line breaks are `\r`, the theme or plugin "header" becomes inaccessible.
 This is browser and OS dependent but seems all modern browsers work with
 `\n` line breaks in a textarea. So the patch can be as simple as:
 {{{
 srt_replace( array("\r\n"' "\r"), "\n", $content );
 }}}
