If in a

 block a quote (single or double) is followed by a closing parenthesis the rendered version displays a spurious semicolon inbetween the two.  E.g.

  

foo("bar")

is rendered as:

<div class="preformatted"><div class="preformattedContent">
<pre>foo("bar&quot;)</pre>
</div></div>

which looks like:

foo("bar"

As a workaround I was able to backslash escape the closing parenthesis.
