Inject Iframes

[Xilonz]

Iframes aren't injected with the krypton javascript.

Use case: I use Bitwarden as password manager, and it uses an iframe (https://vault.bitwarden.com/u2f-connector.html?data=...) in their extension to load an page that triggers the u2f-key. Opening that iframe in a seperate window injects the javascript, and krypton works.
