is org-export-preserve-breaks incompatible with org verse blocks?

[mousebot]

hi org,

i use verse blocks to export to odt in a way that preserves whitespace. if i 
enable org-export-preserve-breaks, whitespace in verse blocks is not preserved: 
any spaces used to indent text from the left margin are reduced to a single 
space. is this intended behavior? i had hoped to be able to use both features 
in my document.

example:

#+begin_verse
here you are,
        doing your
    darned
              best
to export
#+end_verse

will export as

here you are
 doing your
 darned
 best
to export

i tested this by loading emacs -Q, evaluating (setq org-export-preserve-breaks 
t), then using the normal org export dispatch, with no template.
