  1. Action.OpenUrl with a top-level browsing context 

    While HTML links [launch without an opener reference][spec],
[`window.open`][vulnerability] provides a reference to the parent page
through an auxiliary browsing context. Given untrusted URL input, this
can lead to tabnabbing and phishing attacks.

This change uses the [noopener] and [noreferrer] [window features] for
the default link handler in the React renderer.

[spec]: whatwg/html#4078
[vulnerability]: https://mathiasbynens.github.io/rel-noopener/
[window features]: https://developer.mozilla.org/en-US/docs/Web/API/Window/open#windowfeatures
[noopener]: https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/rel/noopener
[noreferrer]: https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/rel/noreferrer
