XPConnect generally throws when trying to create instances of non-DOM objects in content. Due to some bugs this has historically worked in certain cases, but we're fixing those now. So we need to fix the tests that do this sort of thing.

// Bug 762939 - Test that visibility propagates down properly through

// hierarchies of <iframe mozbrowser>.
|
|
//
|
|
// In this test, we modify the parent's visibility and check that the child's
|
|
// visibility is changed as appopriate. We test modifying the child's
|
|
// visibility in a separate testcase.
