/**
|
|
* Test for Bug 1339722
|
|
* 1. Wait for "http-on-modify-request" or document-on-modify-request for the
|
|
* iframe load.
|
|
* 2. In the observer, access it's window proxy to trigger DOMWindowCreated.
|
|
* 3. In the event handler, delete the iframe so that the frameloader would be
|
|
* destroyed in the middle of ReallyStartLoading.
|
|
* 4. Verify that it doesn't crash.
