write some markdown representing a codeblock, i.e. <pre><code>...</code></pre> : expected false to be true

#preview does not contain at least one <pre> : expected +0 to be at least 1
Follow this to write a codeblock in markdown, it’s the isntructions to write a codeblock on the forum, but the same identical syntax is for there:
When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.
You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.
