"Stacking order" and "foreground" are 2 different things.  As I wrote
earlier, a "foreground" window/frame is the window that has focus and
gets the keyboard input.  It doesn't have to be on the top of the
Z-order.

No, it keeps focus in new-frame, but makes it so the input you type at
new-frame gets sent to old-frame.  Thus, this:

is normal and expected behavior (AFAIU).
