In that case I get with emacs -Q on the release branch the following in
my *Messages* buffer:
Composing main Info directory...done
(#<window 3 on *info*> 173 (0 . 0) 0 (#("(dir)Top
" 0 8 (font-lock-face info-header-node)) . 0) 173 (0 . 0) nil (0 . 0) (9 . 18))
Tab-Line mode enabled in current buffer
(#<window 3 on *info*> header-line (8 . 18) 0 (#("No next, prev or up links --
This is the top of the INFO tree" 31 63 (fontified nil)) . 0) nil (0 . -1) nil (8 . 1) (9
. 18))
