add a bug# to track down the real cause.

i would remove instanceof based checks.  JS instanceof is really flaky and
nobody relies on it . Perhaps instead just do some duck typing checks such as
validate that the class has an innerHTML, addEventListener method, etc.
Those sorts of checks are much more likely to work cross browser.

[justinfagnani, 2013/10/23 21:23:57]

I'm going to do an overhaul of this test in it's own CL so that it's easy to
review independent of other changes. I'll remove the instanceof checks then.
