Great, so I'm closing this bug. Thanks to all who supported the
testing of the fix.
P.S. FTR: the fix is on the master branch, so it will be in Emacs
28.1.

Hi all,
With the following sample code, I observe the results shown in the attached image. The first two "ab" have a border, but the last one only has three-quarters of its border: the right side is missing.
(defface my-button
'((t :box(:line-width -4 :style released-button)
:background"lightgrey":foreground"black"))
"Button face")
(with-current-buffer (get-buffer-create "button")
(insert "\n")
(insert (propertize "ab" 'face 'my-button))
(insert " ")
(insert (propertize (compose-chars ?a '(Br . Bl) ?b) 'face 'my-button))
(insert " ")
(insert (propertize "ab" 'display (compose-chars ?a '(Br . Bl) ?b) 'face 'my-button))
(insert " ")
(pop-to-buffer-same-window (current-buffer)))
Clément.
