On review feedback, I had changed the mode selector rendering to use

Spina's renderInto() method. This was not passing the correct element

to render into, but I didn't notice, because renderInto() had a bug

that prevented the menu from rendering at all.
This change also adds an extra call to #update() when we render, just

to ensure that it will always have the correct data.

Used the banner and once again saw the mode selector menu.
