While my spaces appear to be maintained, it's unfortunately still performing additional line break processing, making every line break a double link break. Not sure what the configuration interface looks like, but there should be no further processing inside these tags. Since it's rendered as a <span style="white-space: pre;"></span> instead of <pre></pre>, the additional line breaks are being rendered when rather the any code in the <pre> should be shown as code, i.e. <br>.
