target=”_blank” disappearing in html pane. Not letting me open link in newwindow

I am trying to insert this html code in the html pane on a page. I know my links and everything works fine, however after i place it in the html pane and switch to the visual pane the target=”_blank” is removed. It is crucial that the link open in a new window. Please GOSH help me!!

This is for a business so the links/emails/passwords have been removed.

<form name=”loginForm” action=”https://awebsite.com&#8221; method=”post” target=”_blank”> <input type=”hidden” value=”a log in email” name=”email”>
<input type=”hidden” value=”passoword” name=”password”>
<input type=”image” src=”where_my_image_comes_from” alt=”Submit” name=”submit”
