qTranslate X integration

Hi,

After updating to the new version of your plugin, it seems like some of the qTranslate X support has been deprecated.

Our Mailchimp form used to be:

[:en]<div id="newsletter-form">
	<div class="label-div"><label>SUBSCRIBE TO OUR MAILING LIST FOR UPDATES</label></div>
	<div>
<input type="email" id="mc4wp_email" name="EMAIL" placeholder="Your Email Address" required />
<input type="submit" value="Sign up" />
</div>
</div>[:zn]<div id="newsletter-form">
	<div class="label-div"><label>郵件訂閱獲取更多新品信息</label></div>
	<div>
<input type="email" id="mc4wp_email" name="EMAIL" placeholder="您的郵箱" required />
<input type="submit" value="註冊" />
</div>
</div>

Since updating, both options are displayed on the front end, which makes me think that the CodeMirror field is not accepting the conditionals. We have also tried the typical HTML comment conditionals, to no result.
This technique is working perfectly on the text fields in the Messages tab, which makes me think that the conflict is there.

Would you mind pointing in the right direction?

Many thanks.
