bug#65105: Reusing the same string as 'display on consecutive characters

Subject: bug#65105: Reusing the same string as 'display on consecutive characters evades display

Evaluate:

(let ((s1 "test1")
      (s2 "test2"))
  (insert "\n"
          (propertize " " 'display s1)
          (propertize " " 'display s1)
          (propertize " " 'display s2)
          (propertize " " 'display s1)))


The first space display does not take effect, since the s1 string is used for 
two consecutive characters.  This has a practical impact for font-lock backends 
that use the ‘display text-property and would like to minimize string 
allocation.  

Tested Emacs 27/28/29.
