CSS for buttons is not showing up on WordPress 3.9

It appears that it is a core issue, it works on the first commit but the second commit it no longer works.

1. https://github.com/WordPress/WordPress/blob/aa1505ead2d2b3fd65f1d4b85e9024b5b77bc2fe/wp-includes/css/editor.css
2. https://github.com/WordPress/WordPress/blob/bfaf007e97fe795f6b3baae7831a3576796c24f0/wp-includes/css/editor.css

Edit: the missing code is below
‘.quicktags-toolbar input {
margin: 2px 1px 4px;
line-height: 18px;
display: inline-block;
min-width: 26px;
padding: 2px 4px;
font: 12px/18px “Open Sans”, sans-serif;
color: #464646;
cursor: pointer;
border: 1px solid #c3c3c3;
-webkit-border-radius: 3px;
border-radius: 3px;
background: #eee;
background-image: -webkit-gradient(linear, left bottom, left top, from(#e3e3e3), to(#fff));
background-image: -webkit-linear-gradient(bottom, #e3e3e3, #fff);
background-image: linear-gradient(to top, #e3e3e3, #fff);
}’

wormeyman,

I have added in the CSS for the next update of WP Editor.

This has been fixed in the latest version of WP Editor 1.2.5.
