Apparently the V8 bindings treat assigning undefined to a boolean attribute as "true" but it probably should be "false" (need to verify with other browsers).

Interesting. For some reason there isn't an issue when the test is run on the Apple Mac port. I'll investigate shortly.

Maybe the common thread is windows?

We do not appear to have diagnosed the test failure correctly.
