By stepping through srb-shrink-test-1 with edebug, I have seen the
reduction in frame-height occur in two places (on two different
invocations of srb-shrink-test-1 after emacs -Q): as above, after the
(sit-for 0.5) that immediately precedes (delete-other-windows), but also
after the (sit-for 0.5) that follows (delete-other-windows).

I loaded the info library, did `M-x customize-variable RET
Info-use-header-line RET', clicked it to off with toggle button and set
it for the current session. Then I invoked srb-shrink-test-1 and the
Info buffer came up without a header line (C-h v header-line-format in
that buffer said its value is nil). Did you do the same thing and get a
different result, or did you do something else?
Anyway, even without the Info header line, frame-height got reduced by
one line just as with the header line. I also tried just loading info
and running srb-shrink-test-1 with the line (info) commented out: in
this case, frame-height did not change.

I tried variants of srb-shrink-test-1, respectively replacing (info)
with (ruler-mode 1), (tabbar-mode 1) (tabbar.el is an external library
that sets up a tabbed header line), and (setq header-line-format
"TEST"), but in each case frame-height did not change. It seems that
the header line is not relevant, but invoking info is.

I strongly suspect this is the case. Unfortunately, I know nothing
about the gtk-qt engine and it seems that none of the core Emacs
developers uses it.

Yes, unfortunately.

The frame-height reduction happens both with -Q as well as with my
personal settings, which use a different font. I also tried it after
setting all the oversized Info faces to default and still got the
frame-height reduction.
