optional nit: I think passing the element would make this clearer new
window.sidebar.Sidebar($('sidebar'));

[mbrunson, 2016/12/07 01:12:14]

Ah. I agree. Done.

+    PageManager.addObserver(sidebar);

I think we should ask someone from WebUI if there are any technical reasons why
we have to use the singleton pattern. IMO explicitly initializing the page here
would be clearer.

[mbrunson, 2016/12/07 01:12:14]

There doesn't seem to be a technical reason. It works fine either way and there
are a few places that just use "new". I'll stray away from the singleton pattern
for now.
