[BUG] Agenda no longer works for timestamps inside properties drawer [9.5.2 (release_9.5.2-24-g668205 @ /home/ignacio/repos/emacs/lisp/org/)]

[Ignacio Casso <ignaciocasso@hotmail.com>]

Hello,

In Emacs 27.2, with an up to date version of org from ELPA (9.5.2),
org-agenda considers timestamps that appear in property drawers, so the
entry below appears in the daily agenda view.

* Heading
  :PROPERTIES:
  :timestamp: <2022-03-12 sáb>
  :END:

However, in the latest Emacs version built from source (29.0.50), with
the built-in version of org (also 9.5.2, but the latest release, I
assume), this is no longer the case and that entry does not appear in
the agenda view.

I know that maybe it's unorthodox, but I have some org files that rely
in the previous behavior, with entries like the following:

* Some friend
  :PROPERTIES:
  :birth-date: <1994-03-12 sáb +1y>
  :END:

Is this a bug? If it's not, can someone point me to the functions I need
to touch to restore the previous behavior? Or maybe I should stop doing
this and start moving those timestamps out of the properties drawer in
my files?

Regards,

Ignacio
