When I tried to use HTML editor
some HTML tag closed position changed automatically and that messing up layout

ex:

<div id="middleWrapper"> 
    <div id="middle"> 
    <div class="padTop30"><!-- --></div> 
    <div class="containerCareer"> 
   
    <div class="cuLft2"> 
    ...
   </div>
    	<div class="cuLftIn"> 
           ...
      </div>

</div>
</div>

.......
 

became like this after save:

 <div id="middleWrapper"> 
    <div id="middle"> 
    <div class="padTop30">
    <div class="containerCareer"> 
   
    <div class="cuLft2"> 
    ...
   </div>
    	<div class="cuLftIn"> 
           ...
      </div>

</div>
</div>
</div>

It seems like Editor doesn't like tag when there is nothing inside of tab.

How can I prevent editer changing something like this?
