New description:

 Starting from Wordpress 4.3.x TinyMCE started stripping out zero-width
 spaces (\u200B) from posts which essentially destroys line-break
 formatting in the Khmer language (especially on mobile devices). This bug
 was removed once already four years ago (#21025) and so it is a
 regression. We've alerted the TinyMCE team
 [https://github.com/tinymce/tinymce/issues/2859 on GitHub] but also wanted
 to alert the Wordpress team so we can see this fixed.
