After T175937 was resolved, I was hoping that posts could be extracted with something as simple as

$( 'article' ).map( function( i, e ) {
	return $( e ).text();
} );

When I tried this, I noticed that many Flow posts start with "\n\t\t\t\t\t\t" (a line break and six tabs) and ends with "\n\t\t\t\t\t" (a line break and five tabs). Some posts start with "\n\t\t" and end with "\n\t". There does not seem to be – as far as I'm able to discern – any pattern to this, i.e. it does not seem to be related to indentation of the post.

Is this intentional? Where does it come from?
