Looks good to me. It doesn’t actually apply here, so I did it
manually. I suspect it just needs rebased onto a more recent commit or
something.

If you put the top of the child frame off the top of the screen, then
click on it, it jumps back down so the titlebar is visible again. Is
this intentional?

I can’t find this in CONTRIBUTE, but you’re allowed to specify
#ifdef’d code with something like:

* src/nsterm.m (constrainFrameRect:toScreen:) [NS_IMPL_COCOA]:
Constrain non-child frames if they would otherwise go offscreen.

Thanks for working on this. :)
