bug#27517: 26.0.50; 25.2.2; Cannot add "help-echo" property to buffer regions.

[Vitalie Spinu]

Hi,

Do

 (put-text-property (point-min) 100 'help-echo "my-mouse-over" (current-buffer))

No "help-ehco" property is added. Any other property (including special
properties) can be added.

Same problem with emacs 25.2.2, but works in emacs 24.5.1.
