The latest version of wetkit seems to break the secondary menus moving up to the "Search and menus" section. In the previous version the sidebar menus (marked as "sidebar" in the menu block settings) move up into the hamburger menu on narrow displays. The latest version still shows them in the search and menus but also leave them displayed in the page content.
This is the wet docs for the types of menus we're using:
You can see this live on the http://consultation.crtc.gc.ca site now.
Wanted to confirm this is a bug and not a change to how the wet specification deals with secondary menus.
