It looks like it pretty much works, with a couple caveats. Thank you.

Resizing and repositioning works. company-posframe functions with a GTK3 
build like it does with a GTK2 build.

Caveats:

- The thing with "resize then refresh" is also here. When a frame is 
resized, two distinct phases are also visible sometimes. But if it's the 
best we can do with GTK... *shrug*

- The original test case in this thread shows a glitch in the child 
frame in the place (to the right) where the scroll bar could be. See the 
attached screenshot. Resizing the frame (height or width) doesn't make 
it go away. posframe doesn't trigger this, probably because it disables 
scroll bars.
