Uncomplete export (with "Copy as...") of a block that contains blocks with #+BEGIN_xxx / #+END_xxx (xxx=NOTE, WARNING, ...)

When I export (with “Copy as…”) a block that contains text between #+BEGIN_NOTE and #+END_NOTE, that text between those marks don’t appear in the exported text.

You can check this by creating a block like this:

#+BEGIN_NOTE
Text that isn't exported with "Copy as..."
#+END_NOTE

and using the right button over the bullet, choosing “Copy as…” You´ll see that the wrapped text doesn’t appear in the exported contents.

I use version 0.9.1, for Windows 64bit
