Yes, with (a gtk3 build of) current master I still get frame resizing
both with my original recipe and with Martin's pixelwise adjustment.
For the latter, here are the outputs

with frame-resize-pixelwise nil:

Emacs started; frame pixel height: 648  toolbar height: 42
Gnus started; frame pixel height: 648  toolbar height: 42

Other buffer; frame pixel height: 666  toolbar height: 42
Back to Summary buffer; frame pixel height: 701  toolbar height: 7
Final; frame pixel height: 684  toolbar height: 42

and with frame-resize-pixelwise t:

Emacs started; frame pixel height: 648  toolbar height: 42
