I don't know if it's me, but, nope, it does not.

Look, I'm starting from such a node:

--8<---------------cut here---------------start------------->8---
* Current assets

** DB
*** Model
**** Schema
**** Partial X
     We extended X in order to put constraints on things (as one can
     with cardinalities).
**** What
*** Rules
**** Other
***** First
***** Second
***** Rules, with link automatically made between rule failures and 
contributing properties
**** Performance
***** Specialization of programs given partial data
***** Query reduction: optimize the queries so that with a minimal IO 
interaction the necessary data from a DB can be requested
*** Computations
**** Excel engine *IS NOT THE LAST ITEM*
*** Integrity *has a subitem* (not shown by default)
**** Seamless migrations is not visible if allowframebreaks is not set
--8<---------------cut here---------------end--------------->8---

Trying to add the property on the level-2 item named "DB", as you can see in
my "lossage":

--8<---------------cut here---------------start------------->8---
M-x o r g - b e <tab> a m e r <tab> m o <tab> <return>
M-x <up> <return> C-c C-x C-c <right> e b e e <tab>
[ a l l w o <backspace> <backspace> o w f r a m e s
<backspace> b r e a k s ] <return> q q <tab> <tab>
<tab> <tab> <tab> <down> <tab> <down> <tab> <up> <tab>
<tab> <up> <tab> <tab> C-h C-h l
--8<---------------cut here---------------end--------------->8---

I end up with that change:

--8<---------------cut here---------------start------------->8---
* Current assets

** DB                                            :[allowframebreaks]:B_block:
*** Model
--8<---------------cut here---------------end--------------->8---

Properties are empty.

When not typing `e b', I just end up with:

--8<---------------cut here---------------start------------->8---
** DB                                                    :[allowframebreaks]:
*** Model
--8<---------------cut here---------------end--------------->8---

No property block is created...

Maybe I still do something wrong?

As soon as I get this working, OK, yes, not a problem, I just have to know...
