bookmark link sort does not work well.

I found ‘function wp_list_bookmarks”s optional parameter does not work well.
For example, if I tried to set ‘&orderby=id’ to sort the link by id, the link list did not be changed.

So, I checked the code and found a problem in code L.223 on /wp-include/bookmark.php.

function get_bookmarks{—
(L.223) case ‘link_id’:
—}
It should be,
case ‘id’:

I think that some more ‘case’ for ‘wp_list_bookmarks()”s parameter setting, isn’t it?
I am not good at understanding PHP codes.
I hope someone to check around here.

Thank you.
