/*
When an iframe is created it will contain the initial empty document. If the
src is set to a URL that doesn't load a new document (e.g. it results in a
HTTP 204 response), it will stay on the initial empty document. After fragment
navigations happen on it, it should still stay on the initial empty document.
These tests verifies the behavior of navigations that happen on the initial
empty document in that situation. They should all be converted to do a
replacement.
