Confirmed.
This is related to point adjustment and the way column view works.
Column view puts N overlays onto first N chars on the heading line.
However, when a char has invisible property (which [[ in link do), even
though there is something displayed on top, Emacs still adjusts point,
trying to skip over "invisible" text.
To illustrate:
(let (ovs)
(with-current-buffer (generate-new-buffer "*temp*")
(display-buffer-below-selected (current-buffer) nil)
(insert "\n\n12345789")
(goto-char (point-min))
(with-silent-modifications
(search-forward "1")
(backward-char)
(put-text-property (+ (point) 2) (+ (point) 4) 'invisible t)
(read-char "Press any key (part of 123456789 hidden)")
(dolist (offset '(0 1 2 3 4 5 6 7 8))
(push (make-overlay (+ offset (point)) (+ offset (point) 1)) ovs)
(overlay-put (car ovs) 'display (copy-sequence "!")))
(message "NOW, move cursor across 123456789 string, observe point jumping
across some !"))))
I will report this to Emacs devs and see what they say.
