No reason other than being cautious and "follow the traditional behavior
of blink-matching-open". The code that I extracted from
blink-matching-open to reuse it for show-paren-mode removed the text
properties (see
https://git.savannah.gnu.org/cgit/emacs.git/tree/lisp/simple.el?h=emacs-28#n8608).
If I'm not mistaken, this was apparently introduced in 2005 by Richard
Stallman
(https://git.savannah.gnu.org/cgit/emacs.git/commit/?h=emacs-28&id=1d0e3fc84f058248515f242c0484a0dabfac95aa),
but I don't know the reasons for the change. Perhaps it didn't look
good on some TTY frames?
