Eli seems to have had the right idea. I rebuilt with

  ./configure --with-x-toolkit=gtk3 CFLAGS='-Og -g3'

and:

1. When trying to resize the child frame, adjust_frame_size (...) *is* 
hit. "configureEvent = ..." is not hit.

2. When moving the child frame by dragging the mode-line (or any other 
way), the second breakpoint is hit.

The first one (if (FRAME_WINDOW_P (f)) ...), -- isn't hit when dragging 
the mode-line. It *is* hit if I call set-frame-position explicitly from 
Lisp.
