Fix for iOS back/forward button when using CSS animations to load in and out the content.

AnimateOut.js

const $container = document.getElementById('container')

window.onpageshow = (e) => e.persisted ? window.location.reload() : null

export default function(href) {
	document.body.classList.remove('load-in')
	document.body.classList.add('load-out')

	;['animationend', 'webkitAnimationEnd'].map(evt => {
		$container.addEventListener(evt, (e) => {
			location.href = href
			$container.removeEventListener(e.type, arguments.callee)
		})
	})
}
