// 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.

// For the purposes of this test, we want there to be a process barrier
