Crayon splitting code across dozens of lines

Can someone tell me what’s going on here? My code is being split across dozens of lines a keyword or character at a time!

Excerpt from page source; only the comments stay on a single line:
…
<span class=”crayon-cn”>1</span>
<span class=”crayon-sy”>,</span>
<span class=”crayon-h”> </span>
<span class=”crayon-cn”>2</span>
<span class=”crayon-sy”>,</span>
<span class=”crayon-h”> </span>
<span class=”crayon-cn”>3</span>
<span class=”crayon-sy”>,</span>
<span class=”crayon-h”> </span>
<span class=”crayon-cn”>4</span>
<span class=”crayon-sy”>]</span>
<span class=”crayon-sy”>;</span><span class=”crayon-h”> </span>
<span class=”crayon-c”>//myArray contains the elements 1, 2, 3, 4</span>
…

BUT– when I click on the ‘Open in new Window’ button, the code is highlighted normally:
