9840	buttons on 4th line don't get added if 3rd line is empty	Denis-de-Bernardy	azaozz	"I'm not entirely sure this is due to WP or TinyMCE, but:

{{{
add_filter('mce_buttons_3', 'my_editor_button'); // adds the button

add_filter('mce_buttons_4', 'my_editor_button'); // ignores the button
}}}

I'm pretty sure we can work around this if it is TinyMCE-related -- patch I've in mind coming up in a bit if it works."	defect (bug)	closed	normal	2.8	TinyMCE	2.8	normal	fixed	has-patch tested commit
