The change on its own is wrong. There is nothing special about direct
child of top HTML window. Ideally, we should call FireBeforeNavigate2
for all HTML windows, but use super_navigate only for the main one. This
means that the if you change should not check which window we're in at
all. However, for other windows, we need to pass proper frame name
there. Let me know if you need more details.
