Yes, with pop-up-windows set to nil, I can reproduce it too.
The problem is that truncate-lines is set to t inside org-insert-link.
When I comment that out, I get the behavior you expect. The question is:
why is truncate-lines set to t? I don't know the answer to that, but it
seems to be unnecessary: I think it could be let-bound instead or explicitly
reset to its former value afterwards.

The problems described by Samuel in the link you provided may be caused 
by the same setting, but I haven't looked in detail.
