With bidi-paragraph-direction=right-to-left, replacing 'display properties are sometimes reversed on the 1st displayed line of text.
(let* ((w (window-font-width))
(h (window-font-height))
(face )
(str (cl-loop for col in '("red" "green" "blue" "cyan")
concat " "
concat (propertize " " 'face `(:background ,col)))))
(dotimes (i 10)
(insert "\n" (propertize " " 'display str) (format ";; line %d" i))))
Evaluate in *scratch* and scroll the color bars off the top of the screen. Try again with bidi-paragraph-direction=right-to-left and the color order will invert and the bars shift by one char.
Verified in Emacs 29 emacs-mac and NS builds.

No further comments, so I presume the bug is indeed fixed, and I'm now
closing it.
