Comment (by briansahagun):

 The second link shows that even in the HTML source, the content of <pre>
 has no formatting.

 Twenty Seventeen does not have any OB–what I meant to say is that I
 switched theme to ensure that the same content is ok without OB (as seen
 in Twenty Seventeen theme).

 I already tried putting the_content() outside OB (using my theme) and
 <pre> works as expected.

 But when put inside OB, the formatting gets discarded.

 Here it is:

 The first CSS is the_content() outside OB. The second CSS is within OB.

 and view it using my theme (wherein I run the_content() inside ob_start()
 ), the formatting is removed.

 > The second link shows a 403 error. If output buffering works as expected
 in Twenty Seventeen but not in your theme, it sounds like the issue is
 somewhere in your theme rather than in WordPress core. Could you track it
 down further?
