Yes it does.

Sure thing:

Emacs 29:

emacs -Q
(frame-geometry): ((outer-position 1127 . 81) (outer-size 1384 . 1504)
(external-border-size 28 . 34) (outer-border-width . 0) (title-bar-size 0 .
46) (menu-bar-external . t) (menu-bar-size 1328 . 50) (tab-bar-size 0 . 0)
(tool-bar-external . t) (tool-bar-position . top) (tool-bar-size 1328 . 82)
(internal-border-width . 0))
C-x 5 2
menu-bar-mode RET
(frame-geometry): ((outer-position 1127 . 81) (outer-size 1384 . 1454)
(external-border-size 28 . 34) (outer-border-width . 0) (title-bar-size 0 .
46) (menu-bar-external . t) (menu-bar-size 0 . 0) (tab-bar-size 0 . 0)
(tool-bar-external . t) (tool-bar-position . top) (tool-bar-size 1328 . 82)
(internal-border-width . 0))
C-x 5 2
(frame-geometry): ((outer-position 28 . 90) (outer-size 456 . 570)
(external-border-size 28 . 34) (outer-border-width . 0) (title-bar-size 0 .
46) (menu-bar-external . t) (menu-bar-size 0 . 0) (tab-bar-size 0 . 0)
(tool-bar-external . t) (tool-bar-position . top) (tool-bar-size 400 . 82)
(internal-border-width . 0))

Emacs git master (commit 92ea393a16e):
emacs -Q
(frame-geometry): ((outer-position 28 . 90) (outer-size 1384 . 1504)
(external-border-size 28 . 34) (outer-border-width . 0) (title-bar-size 0 .
46) (menu-bar-external . t) (menu-bar-size 1328 . 50) (tab-bar-size 0 . 0)
(tool-bar-external . t) (tool-bar-position . top) (tool-bar-size 1328 . 82)
(internal-border-width . 0))
C-x 5 2
(frame-geometry): ((outer-position 108 . 170) (outer-size 456 . 620)
(external-border-size 28 . 34) (outer-border-width . 0) (title-bar-size 0 .
46) (menu-bar-external . t) (menu-bar-size 400 . 50) (tab-bar-size 0 . 0)
(tool-bar-external . t) (tool-bar-position . top) (tool-bar-size 400 . 82)
(internal-border-width . 0))

The window manager is mutter, I suppose?
