Hi,
When I use emacs 24.3.1 and run
/usr/bin/emacs -Q
Then M-< followed by M-x global-hl-line-mode and M-x describe-face, emacs asks
me
Describe face (default `font-lock-comment-delimiter-face'):
But when I use 26.1 and run
/usr/local/bin/emacs -Q
and run exactly the same commands, emacs asks me
Describe face (default ‘hl-line’):
I have to turn hl-line off to get the name of the point's face. This makes the
default value of the function useless.
It seems that
(get-char-property (point) 'face)
returns hl-line in 26.1, but returns the actual face in 24.3.1.

I can reproduce this, but for me both Emacs 26 and Emacs 24 behave the
same. So I don't know why your Emacs 24 behaves differently, perhaps
it's due to some local changes that are not in upstream sources.
In any case, "M-x describe-face" is not the right tool when there
could be several text properties at the same position, because
describe-face can only name one face, and it selects the one that
affects the text the most. I suggest to use another command instead,
"M-x describe-text-properties". It will pop up a window with
information about all the properties at point, and you can then drill
down using the buttons in that window.
This is not a bug.
Thanks.
