supporting menu_minipanels

I don't think this is the same issue #1314210: Сompatibility with Menu Minipanels module.

Minipanels should appear when hovering over a menu item, but they don't, even when I have implemented your hook_page_alter() fix.

The rendered menu contains <a ... class="menu-minipanel menu-minipanel-1159">.

I haven't wrapped my mind around the issue yet, but this section in menu_minipanels.module might be relevant.

Would you add support for menu_minipanels in Corolla 7.x-3.x?

/**
 * Implements hook_theme_registry_alter().
 *
 * Theme preprocess functions aren't called if the theme is in a function.
 *
 * This hacks a preprocess function for theme_menu_link in a way that
 * won't interfere with other themes or modules that override
 * theme_menu_link.
 *
 * theme_menu_link is overriddeden because to print menus, themes and
 * modules generally use menu_tree_output, and menu_tree_output calls
 * theme_menu_link.
 *
 * This method *only* works if theme_menu_link is called *before*
 * $closure is created in page_preprocess.
 *
 * If a theme calls theme('menu_tree') in a page.tpl.php for instance, this
 * will not work.
 *
 * To get it to work, the theme will need to implement page_preprocess hook
 * and add a variable to $vars, so that the theme_menu_link is called
 * *before* $closure.
