Subject: [PATCH] Attempt to reduce intermittent failures in the "cleans up
 document resources during rendering of page" unit-test

This patch should *hopefully* remove the `Unhandled promise rejection: ...` errors, by returning the "final" promise. Also, by pausing/delaying of rendering slightly the likelihood of the test failing in the first place should thus be reduced.
