Warning span background image on update.php makes update dependencies unreadable.

Thanks for this info

This patch should fix that behavior by adding the 'messages' class to the div.

Tested this manually and it works great, thanks! Moving to RTBC.

If someone else want to test this manually, the fastest way is to define an empty hook_update_N() in one module .install file, then add a hook_update_dependencies() to the same .install file and require a non-existing update from other module. Like this:

function comment_update_dependencies() {
  $dependencies['comment'][7010] = array(
    'block' => 7010,
  );
  return $dependencies;
}

Then the update.php will display the dependency warning like the one in the IS. After applying the patch the warning is readable again.

Thanks everyone!
