* `setTimeout` and `clearTimeout` are global functions. Think the window versions of them were for the following reason: https://stackoverflow.com/questions/60245787/
* Comments and extra test here helped me understand which inserts were expected and which are to be ignored
* Add a test for the style setProperty/removeProperty added in #671
* Add a test to ensure that listeners get added correctly in nested iframes - particularly important for those which rely on prototype monkeypatching
* Pass in the window object from the current iframe so that monkeypatching applies to all windows
* Satisfy typings
* No need to insert an iframe as there's one already set up for us
* Enable the console logger to also intercept log messages within iframes
* There's no tests for FontFace but presumably the monkeypatching here works similarly to the others
