Should this check both documents? (I'm not sure what the HTTP-family check is *for*, so the answer could easily be yes OR no, I'm not sure)

Good question! So I *think* the top document URL check should suffice.

As far as I understand, this check is here because the feature that this "modal container observation" mechanism drives is only intended to take effect when navigating to http URLs, as opposed to file:// or any custom schemes, so this basically just acts as a way to short circuit the detection logic early on in the case where the document isn't HTTP/HTTPS.

In the subframe case in particular, the..."semantically interesting" content of the modal container can come in the form of a data: URL on the iframe or the `srcdoc` attribute, in which case the URL will not be in the HTTP family (but we'll still need to descend into these frames for the purposes of modal container detection) — so in the case where the sub-document is non-HTTP-family, we don't want to bail early here.
