bug#61580: line-prefix and display text properties cause odd cursor movement |

When moving the cursor up and down on lines which have both line-prefix and display text properties, the cursor column isn't preserved, jumping ahead or back by a fixed amount.
This can be reproduced with the following config
(add-text-properties 12 13 '(line-prefix " "))
(add-text-properties 27 28 '(line-prefix " "))
(add-text-properties 57 58 '(line-prefix " "))
(add-text-properties 72 73 '(line-prefix " "))
(add-text-properties 12 13 '(display "•"))
(add-text-properties 27 28 '(display "•"))
(add-text-properties 57 58 '(display "•"))
(add-text-properties 72 73 '(display "•"))
and this input file (which mimics org-indent).
* h1
** h2
- a.y.........
- x...........
*** h3
**** h4
- ....w.......
- z...........
With the cursor on x, pressing up moves it to y instead of a, and pressing down moves it back to x. The amount moved depends on the indentation added by line-prefix: with the cursor on z, pressing up moves it to w.
