|
// 1. when the iframe's document finishes printing.
|
|
// 2. when the iframe's document finishes loading its own <object> child-document.
|
|
// When those two steps have completed, we're past the situation that would
|
|
// trigger a fatal assertion when the object document gets cycle-collected.
|
|
// So at that point we remove our iframe, and (after a rAF tick) trigger a
|
|
// GC and CC, and then consider the test as having passed if we're still
|
|
// alive at that point.
