If you have this check anyway, why do you need the one in the renderer? Just
fail here and show the blockage icon.

The problem is that we want to have the Page Action show up when the page is
rendered, instead of having UI show up when the form is being submitted.

Wait, so you want to show something in the omnibox anytime any webpage has a
<keygen> element, even if it's never used? Isn't that a bit overkill?
