This is an example of what a code-block will look like in the Editor’s pretty view, if I include the attribute ‘class=”language-markup”‘ in the <code> tag, but not in the <pre> tag, as it was meant to be:
Line 1
Line 2
Line 3
This is an example of what I get, when I put the same attribute into the <pre> tag as well:
Line 1
Line 2
Line 3
However, in the publicly-viewable style, both examples display correctly.
