This PR hardens the handling of the “open-link” action in render iframes
(external rendering iframes). It prevents iframes from triggering unsafe
or unintended redirects or opening new windows via postMessage.
Additionally, it improves iframe height reporting to reduce scrollbar
and height mismatch issues, and adds unit test coverage.

A big step towards enabling strict mode in Typescript.
There was definitely a good share of potential bugs while refactoring
this. When in doubt, I opted to keep the potentially broken behaviour.
Notably, the `DOMEvent` type is gone, it was broken and we're better of
with type assertions on `e.target`.
