Error rendering Code Block html after saving and updating page

I think this is a bug in the rendering of the Code Block

I input the following code

<form name=”contact” method=”POST”> <input placeholder=’First Name’ type=”text” id=”customer_first_name” name=”first_name” />
<input placeholder=’Last Name’ type=”text” id=”last_name” name=”last_name” />
<input placeholder=’City’ type=”text” id=”city” name=”city” /><br />
<input placeholder=’Your Email’ type=”email” id=”email” name=”email” /><br />
<textarea placeholder=’Your Message’ rows=”4″ id=”message” name=”message”> </textarea>
<input type=”submit”/>
</form>

after saving, and updating the page I see the following code in the avia visual editor

<form name=”contact” method=”POST”> <input placeholder=’First Name’ type=”text” id=”customer_first_name” name=”first_name” />
<input placeholder=’Last Name’ type=”text” id=”last_name” name=”last_name” />
<input placeholder=’City’ type=”text” id=”city” name=”city” /><br />
<input placeholder=’Your Email’ type=”email” id=”email” name=”email” /><br />
<textarea placeholder=’Your Message’ rows=”4″ id=”message” name=”message”>

the </textarea> and subsequent html seems to have been lost in the code block.

Nevertheless if I switch to the code editor the code is correct.
