.current_page_ancestor typo in Twenty Eleven CSS

[zsero]

It's a typo but because of the underscores and dashes it's quite hard to notice. The thing is that .current_page_ancestor is not on a wordpress page, it should be .current-page-ancestor. Note the - vs _.

In detail, instead of:

#access .current_page_item > a,
#access .current_page_ancestor > a {
	font-weight: bold;
}

it should be >>>>

#access .current_page_item > a,
#access .current-page-ancestor > a {
	font-weight: bold;
}

current_page_ancestor is valid. That's what WordPress adds in Walker_Nav_Menu and
Walker_Page:

http://core.trac.wordpress.org/browser/tags/3.2.1/wp-includes/post-template.php#L1032

OK, then there must be a bug somewhere else, because this is what I have in my generated page using stock Twenty Eleven.

menu-item menu-item-type-post_type menu-item-object-page current-page-ancestor menu-item-105

Ah, right. 'current-' . $queried_object->post_type . '-ancestor' is used too:

Actually, duplicate of #18643.
