I start emacs with a minimal .emacs and an empty org file, insert a headline and insert a property drawer with org-insert-property-drawer.
The drawer starts out folded and TAB does not unfold it. I fold the headline and unfold it: the property drawer is now unfolded and TAB does *not* fold it. In addition, the fontification of :PROPERTIES: is wrong: there is no face specified when I check with C-u C-x =, whereas if I add another drawer its "front" has an org-special-keyword face. Other drawers behave normally. IIRC, I had this problem last night, before the recent drawer changes went in, but I didn't try it with a minimal .emacs then. I single-stepped through org-cycle and did not find a place where the property drawer is dealt with: is it supposed to be lumped together with other drawers? If so, it does not seem to work. I did not try any other "special" drawers (LOGBOOK, CLOCK, RESULTS). Can somebody test and confirm/deny?
