MacDue e852aff9e3 LibWeb: Fix crash when loading a HTML string that contains an iframe ...

The HTMLIFrameElement does not create the nested browsing context on
insertion if the document does not have browsing context, which is not
set unless it's the active document.

Previously, in FrameLoader the document was not set as active until
after parsing, which led to iframes without nested browsing contexts,
and crashes.

Fixes #14207
