 I have a shortcode inside a tag attribute:

 {{{
 <a style="color:#d0c900; width: calc([myshortcode]% *10*1 );">
 }}}


 Executing `do_shortcode` returns:
 {{{
 <a style="color:#d0c900;">
 }}}

 Debuging `safecss_filter_attr` I found that if the attribute contains a
 parentheses, the method ignores it. So using: `calc( 100% - 20px )` is not
 allowed
