<h1>
Description</h1>
<p>
This test validates the value of window.performance.navigation.type with a forward
and back navigation.</p>
<p>This page should be loaded with a yellow background frame below. It should turn green for a starting
navigation, back to yellow for a back navigation and then back to green again for a forward navigation.</p>
<p>Along the navigation timeline the frame.window.performance.type is checked for TYPE_BACK_FORWARD.</p>
<p>This test passes if all of the checks to the navigation.type are correct throughout the navigation
scenario and the frame below ends with a green background. Otherwise, this test fails.</p>
