studio theme's red.css has an invalid syntax

studio/library/styles/red.css line 14 there is a double comma (,) between a.comment-reply-link and input[type=submit] as below:

a.comment-reply-link, ,input[type=submit],input[type=button],

the line should read with only a single comma thus:

a.comment-reply-link,input[type=submit],input[type=button],
