Try removing the extra newline between "#+end_quote" and "* baz".

AFAIR this is a long-standing issue in outline, to reproduce without Org
nor specific themes:

1. emacs -Q
2. C-x b repro
3. M-x outline-mode
4. type in: "* foo RET bar RET * baz"
5. move to "bar"
6. M-: 
   (add-text-properties
    (point-at-bol)
    (1+ (point-at-eol))
    '(font-lock-face (:background "red")))
7. S-TAB (to fold all sections)

Here, I see a single column with red background after the ellipses.  If
I add ":extend t" to the face definition, then the whole line has a red
background.
