The overall behavior of the __init__ method has remained the same.
What's changed is how it determines whether a field is explicitly set.

Disabled flaky JS tests pending refactor to Backbone

Placeholder text for <iframe> encourages inaccessible content

When mathjax is down discussion forum doesn't work
as we were using markdown.js with processor as
mathjax. Unavailability of mathjax raise error in
js which stops discussion to render. So I made
markdown independent of mathjax. Markdown now will
use mathjax when it is available otherwise ignore it.
