I'm playing with the help-echo property and it keeps disappearing
for no obvious reason. I would like to confirm the behavior and to
know if this is the intended behavior. Here is a simple example:
(progn
(goto-char (point-min))
(insert (propertize "TEST"
'another-property "Test message"
'help-echo "Test message"))
(goto-char (point-min))
(kill-visual-line) (yank))
Before kill/yank, the string has both the `help-echo` and
`another-property` set, but the yanked string has only the
`another-property` set. This is in text-mode, using Emacs 29.1. I
also observed that in prog-modes, I cannot set the help-echo
property at all (with no warning).

It is intended by default, see the user option
`yank-excluded-properties'.

Many thanks, I did not know this option. Is there a similar things
for prog modes ? For example, if I switch from text-mode to
lisp-mode, the help-echo disappears.

I think this is because lisp-mode adds help-echo to
font-lock-extra-managed-props (see `lisp-mode-variables').

It's described in the elisp manual in the yanking section,
which is fair enough. Perhaps it should also be mentioned
or cross-referenced from the Text Properties section (in
Stickiness of Text Properties or perhaps at the bottom of
Properties with Special Meanings)?

You may want to examine the value of the variable `yank-excluded-properties`. ;-)

This is the intended behavior, see yank-excluded-properties.
