hmm, does this need to be in content? i haven't traced through all the usage of
this, but i'm wondering if chrome is the only place that needs to get/set this,
and it can stash it on the WC using a map or WCUD?

Currently, the New Window API still resides in the content layer. Once the New
Window API is moved to chrome, this will no longer be necessary. I added a TODO
above GetOpener and SetOpener.
