What's the reason for doing both of these things? It seems like this does some redundant work, since `.dropdown("toggle")` calls `clearMenus()`, which removes the `open` class from all dropdown parents. Conversely, since we know for sure we want to remove that class (as opposed to toggling an open dropdown), it seems like just clearing the `open` class should be good enough (it doesn't look like `Dropdown.toggle()` does much more than that).
