Copy and paste formated cross-reference pastes LaTeX code

[Daniel]

When I copy and paste the content of the attached document into some 
rich text supporting word processors, e.g. Libre Writer and MS Word, I 
get some LaTeX code ahead of what I would have expected to be pasted:

\AtBeginDocument{\providecommand\secref[1]{\ref{sec:#1}}}

However, in some other word processors, e.g. Apple Pages, there is no 
additional LaTeX code.

Best,
Daniel
