I did in fact see this lack of height change, but only once among the
probably dozens of times I executed that code before filing the bug
report; I was surprised but since I couldn't reproduce it, I thought it
was a fluke.  All the other times, *Messages* showed this with emacs-25
and master:

Emacs started; frame height: 36
Gnus started; frame height: 36

Tool bar disabled; frame height: 36
Entered Summary buffer; frame height: 36
Tool bar enabled; frame height: 36
Other buffer; frame height: 38
Back to Summary buffer; frame height: 38

With 24.5 the frame height numbers were 35 (five times) followed by 37
(twice).  

When the tool bar was enabled in the Gnus Summary buffer, did you see it
displayed as I describe in the OP: an empty 8-pixel high strip?
