Proposed fix for issue #44840.

This follows other similar tests, such as contain-layout-dynamic-001.html. This stabilizes the test on Blink & Gecko, across multiple hard refreshes.

WebKit, however, requires a double rAF after await document.fonts.ready to stabilize. Without any rAF, WebKit's behaviour is as described in issue #44840. With a single rAF, the test intermittently passes across hard refreshes.
