Er, if this didn't happen, PayPal wouldn't be able to show chrome
indicators.  Among other things, they use Google Analytics.  I think
it would be a perfectly valid thing to refuse to form-submit to a
location that isn't under the same EV Subject as the originating form,
but if you strip the chrome from things that have some non-EV services
you're going to break things.

Even in the case where you require all-EV content, if you try to
perform any additional matching of the Subject (which is what needs to
be matched anyway) you're going to break third-party data feeds and
services.  For example, in the aforementioned case, even if Google
were EV'd, what would the chrome look like?  Whose name would be on
it?  And if that level of paranoia exists, why isn't there a
preference to disable non-EV content and/or EV content where the
Subject on the cert doesn't match the initial request to the EV site?
