Because it was included immediately following a bulleted list, the markdown parser made it part of that bulleted list. Notice how it was indented and how it lines up with the bulleted text:
In order to indicate that code blocks in a bulleted list should be formatted as code, you need to indent lines with eight (8) spaces, rather than the usual four (4). After you do that, everything works fine.
And of course, the reason it worked fine with only 4 spaces here on Meta is because there are no bullets in your question.
