Attachment: Bug 1692052 - Don't notify IMEContext of widget when IMEStateManger doesn't manage this content. r=masayuki

This test case doesn't generate body element and isn't general case. Actually
since we don't manage current IME focus on IMEStateManager, we shouldn't notify
IMEContext of widget.
