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.

Thanks, should be fixed now on the master branch.

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