An additional issue that’s related to the implementation of the
whitelist for invalid certificates that have been overridden for the
duration of the session: the whitelist is stored on the webview, so if I
open a URL for which the certificate has been previously whitelisted in
a new tab, I will get the security warning page again. The whitelist
should be stored on the browser object instead, so that all webviews
share it for the duration of the session.

Title:
  Various issues with security UI's

Bug description:
  I've not done a proper review on this yet, but there are a few issues
  I've noticed just from using the browser:

  - The certificate error UI is displayed for all errors, but it should
  only be displayed for main frame document errors
  (CertificateError.isMainFrame && !CertificateError.isSubresource). You
  can't override other errors anyway, and for subframes and subresources
  it is fine to just block the content (this is how Chrome and Firefox
  behave).

  - When accepting an error, the certificate fingerprint seems to be
  whitelisted by the browser. This is not safe - what happens if the
  user navigates to a genuinely malicious site that happens to use the
  same certificate? If you want to whitelist them, you must also record
  the domain that the error originated from and the error code, and only
  automatically allow the error if the domain + error code +
  fingerprints match

  - When accepting an error, there is no visual cue in the header bar
  that you're on a site with security errors.

  - If you press the stop icon in the addressbar whilst the certificate
  error UI is displayed, the pending navigation is cancelled (returning
  to the previous committed navigation), but the certificate error UI is
  not removed. There is a CertificateError.cancelled signal for this
  purpose - I'm not sure if you're using it or not

  - There doesn't seem to be any indicator when you go to a site that
  has an EV certificate
