Hello,

I encountered a very strange issue with text composition using
prettify-symbols-mode. It happens with text copied from an Org buffer to
Org agenda buffer when the composed text has >4 chars length.

Recipe:
1. git clone https://github.com/yantar92/org
2. cd /path/to/org
3. git checkout feature/org-agenda-fontify
4. make clean
5. make
6. emacs -Q -L ./lisp/ -l org -l /tmp/1.el ~/Org/inbox.org
5. M-x org-agenda < t
6. M-x org-todo on the first item selecting "ONGOING" state
7. Note that "ONGOING" keyword gets replaced with composed icon (as
   defined in 1.el). M-x describe-text-properties shows composition set
   to (0 7 [128119])
8. M-x org-agenda-redo-all
9. The "ONGOING" keyword is not replaced by composed icon anymore. Yet,
   M-x describe-text-properties still shows composition set to (0 7
   [128119])

The 1.el and inbox.org are attached.

Best,
Ihor
