<p>This test passes if there is no assert failure in debug builds and there is no visible
content in the iframe above after the page fully settles.

// We were seeing assert failure when we hid and then re-showed the iframe due
// to a stale graphics layer with an old invalidation posted by the animated
// element. To prevent regression we hide and re-show the iframe, and hide again
// to ensure the content is actually hidden.
