bug#33017: 26.1; no update for displaying glyphless characters

ynyaaa

Evaluate the form below,
characters are displayed as boxed hex numbers.

(dotimes (i 1000)
  (insert (+ #x100000 i) ?\n))

Then type C-v or M-v to scroll up or down.
In some positions of the window, hex numbers for characters are
not updated.

For example, just after evaluation, [1003D7] is displayed on the top line.
Typing M-v repeatedly, [1003D7] remains displayed on the top line.

Thanks, fixed on the emacs-26 branch.

For the record, this has been broken since Emacs 24.4.
