Thanks for your comment!
I tested my code in Chrome, Safari, and Brave by running ``jekyll serve``
and there was no change. As you said, I think this is not a problem with
``<pre>`` not wrapped in ``<div>``.
Instead, I separated ``<pre>`` tag section and text in new commit because
all other codeblocks without this problem is separated from surrounding text.
When I tested it in Chrome, Safari, and Brave, it fixed the problem.
