-------------------------------+-----------------------------
 I have noticed that the TinyMCE buttons markup has changed, which makes
 the custom buttons that we have created invisible, as the CSS selectors
 used to set the icons don't match anymore.

 For example, in 3.8 the following selector is used to set the blockquote
 button icon (in wp-includes/css/editor.css):

 {{{
 span.mce_blockquote:before
 }}}

 and in 3.9 the following selector is used instead:

 {{{
 i.mce-i-blockquote:before
 }}}


 I understand that this is probably the default markup of TinyMCE 4.0, but
 I just wanted to report this issue in case there could be some kind of
 solution to keep the old selectors working, so that there are fewer issues
 with the buttons that the plugin/theme developers create.

 Here is how my custom buttons look like on WP 3.9 Beta 1 - empty line,
 there are several buttons added to the third line (I have highlighted one
 of the buttons with the browser developer tools, just to show that it is
 there):
