[DRE-maint] Bug#833788: Fails to insert <pre> tags around code blocks

Package: jekyll
Version: 3.1.6+dfsg-3
Severity: normal
The packaged version of Jekyll on Debian fails to properly parse code
blocks and fails to insert <pre> tags around them. This causes code
blocks to all render on the same line. This bug appeared after Debian
version 2.2.0+dfsg-2, which correctly inserted <pre> tags, and does not
appear in the upstream version.
For debugging purposes, I've attached a minimal working example
(test.md). Jekyll's behaviour on this example under various versions is
shown below.
Version 2.2.0+dfsg-2 can be fetched using debsnap:
debsnap --binary -a all jekyll 2.2.0+dfsg-2
Upstream's git branch can be installed as follows:

You now have upstream's version of Jekyll installed along with a copy of
every dependency in ~/.gem. To compare its behaviour against Debian's
versions of Jekyll, you can then do:
